Question

if a parallelogram has an area of 48 cm2 calculate : a)height if its base is 5cm b)base if its height is 7cm

Answer 1

Area of Parallelogram = b * h

a) height = Area /base

h= 48/5 = 9.6 cm

b) base = Area/height

b= 48/7= 6.85 cm

Answer 2

Answer:

a) The height is 9.6 cm.

b) The base is 6.85 cm.

Step-by-step explanation:

The Formula for the area of parallelogram is,

Area = Base × Height . . . . . (1)

Given: Area of a parallelogram = 48 $cm^2$

a) To find the height of the parallelogram when the base is 5 cm.

Area = Base × Height

⇒ 48 = 5 × Height

Simplify as follows:

⇒ Height = 48/5

⇒ Height = 9.6 cm

b) To find the base of the parallelogram when the height is 7 cm.

Area = Base × Height

⇒ 48 = Base × 7

Simplify as follows:

⇒ Base = 48/7

⇒ Base = 6.85 cm (Approx.)
