Question

17. The base of a parallelogram is three fourth of its height. If the area is 243sqcm, find the
base and height.​

Answer 1

Answer:

So if the base is double height will remain same , then the area will be double

let it be 3x and 4x

area of parallelogram - b × h

= 243 = 3x× 4x

243 = 12x^2

243 /12 = x^2

20.25 = X ^2

base - 3 x = 3×20 = 60cm

height - 4x = 4×20 = 80 cm

Answer 2

Answer:

• let height of ||g be 'b', then base of ||g be 3b.

so, area of ||g=base×height

➡75cm ^2 =3b×b

➡b^2 =2

➡b=5cm,

◆therefore height =5cm◆
