    Question 1

    Find the area of each of the following parallelograms:

    Answer:

    (a)

    Given height is 7 cm and base is 4 cm.

    Area of the parallelogram is given by,

    Area=Base×Height =4×7 =28

    Area=Base×Height=4×7=28

    Thus, area of parallelogram is

    28 cm 2 28 cm2 . (b)

    Given height is 3 cm and base is 5 cm.

    Area of the parallelogram is given by,

    Area=Base×Height =5×3 =15 cm 2

    Area=Base×Height=5×3=15 cm2

    Thus, area of parallelogram is

    15 cm 2 15 cm2 . (c)

    Given height is 3.5 cm and base is 2.5 cm.

    Area of the parallelogram is given by,

    Area=Base×Height =2.5×3.5 =8.75 cm 2

    Area=Base×Height=2.5×3.5=8.75 cm2

    Thus, area of parallelogram is

    8.75 cm 2 8.75 cm2 . (d)

    Given height is 4.8 cm and base is 5 cm.

    Area of the parallelogram is given by,

    Area=Base×Height =4.8×5 =24 cm 2

    Area=Base×Height=4.8×5=24 cm2

    Thus, area of parallelogram is

    24 cm 2 24 cm2 . (e)

    Given height is 4.4 cm and base is 2 cm.

    Area of the parallelogram is given by,

    Area=Base×Height =2×4.4 =8.8 cm 2

    Area=Base×Height=2×4.4=8.8 cm2

    Thus, area of parallelogram is

    8.8 cm 2 8.8 cm2 .

    Question 2

    Find the area of each of the following triangles

    Answer:

    (a)

    Given, base of a triangle is 4 cm and height is 3 cm.

    Area of the triangle is given by,

    Area= 1 2 ×Base×Height Area=12×Base×Height

    Substitute the given values in the above formula.

    Area= 1 2 ×4×3 = 12 2 =6 cm 2

    Area=12×4×3=122=6 cm2

    Thus, area of triangle is

    6 cm 2 6 cm2 . (b)

    Given, base of a triangle is 5 cm and height is 3.2 cm.

    Area of the triangle is given by,

    Area= 1 2 ×Base×Height Area=12×Base×Height .

    Substitute the given values in the above formula.

    Area= 1 2 ×5×3.2 =8 cm 2 Area=12×5×3.2=8 cm2

    Thus, area of triangle is

    8 cm 2 8 cm2 . (c)

    Given base of a triangle is 3 cm and height is 4 cm.

    Area of the triangle is given by,

    Area= 1 2 ×Base×Height Area=12×Base×Height .

    Substitute the given values in the above formula.

    Area= 1 2 ×3×4 =6 cm 2 Area=12×3×4=6 cm2

    Thus, area of triangle is

    6 cm 2 6 cm2 . (d)

    Given base of a triangle is 3 cm and height is 2 cm.

    Area of the triangle is given by,

    Area= 1 2 ×Base×Height Area=12×Base×Height

    Substitute the given values in the above formula.

    Area= 1 2 ×3×2 =3 cm 2 Area=12×3×2=3 cm2

    Thus, area of triangle is

    3 cm 2 3 cm2 .

    Question 3

    Find the missing values: S.No. Base Height Area of the Parallelogram a. 20 cm 246 cm² b. 15 cm 154.5 cm² c. 8.4 cm 48.72 cm² d. 15.6 cm 16.38 cm²

    Answer:

    (a)

    Given base of the parallelogram is 20 cm and area is

    246 cm 2 246 cm2 .

    Area of parallelogram is given by,

    Area=Base×Height Area=Base×Height

    Substitute the given values in the above formula.

    246=20×Height Height=12.3 cm

    246=20×HeightHeight=12.3 cm

    Thus, the height of the parallelogram is

    12.3 cm 2 12.3 cm2 . (b)

    Given height of parallelogram is 15 cm and area is

    154.5 cm 2 154.5 cm2 .

    Area of parallelogram is given by,

    Area=Base×Height Area=Base×Height

    Substitute the given values in the above formula.

    154.5=Base×15 Base= 154.5 15 Base=10.3 cm

    154.5=Base×15Base=154.515Base=10.3 cm

    Thus, the base of the parallelogram is

    10.3 cm 10.3 cm . (c)

    Given height of parallelogram is 8.4 cm and area is

    48.72 cm 2 48.72 cm2 .

    Area of parallelogram is given by,

    Area=Base×Height Area=Base×Height

    Substitute the given values in the above formula.

    48.72=Base×8.4 Base= 48.72 8.4 Base=5.8 cm

    48.72=Base×8.4Base=48.728.4Base=5.8 cm

    Thus, the base of the parallelogram is

    5.8 cm 5.8 cm . (d)

    Given height of parallelogram is 15.6 cm and area is

    16.38 cm 2 16.38 cm2 .

    Area of parallelogram is given by,

    Area=Base×Height Area=Base×Height

    Substitute the given values in the above formula.

    16.38=15.6×Height Height= 16.38 15.6 Height=1.05 cm

    16.38=15.6×HeightHeight=16.3815.6Height=1.05 cm

    Thus, the height of the parallelogram is

    1.05 cm 1.05 cm .
