Question

The base of a parallelogram is twice its altitudė. If its area is 288 cm2, then its altitude is
(i) 24 cm
(ii) 16 cm
(ii) 12 cm
(iv) 6cm
​

Answer 1

Answer:

• (iv) 6cm

Step-by-step explanation:

Let the height of the parallelogram be x cm.

Then base =(2x) cm

Area of parallelogram =72 cm ^2

2x * x=72cm^2 ⇒2x^2 = 72cm ⇒ x^2 = 36cm

x=6cm.

Hence,

height of parallelogram =6cm.
