Question

The base of a parallelogram is thirce its height. If the area is 867 sq.cm, find the base and height of the parallelogram​

Answer 1

Answer:

3x and x

3x×x=867

3x²=867

x²=289

x=17

Answer 2

Answer:

Area of a parallelogram = Base [b] × Height [h] = 867m²

Also , it is stated that base is thrice its height

⇒ b = 3h

So , Area = 3h × h = 867m²

⇒ 3h² = 867m²

⇒ h² = 867/3 = 289m²

⇒ h = √289 = 17m [approx]

So height [h] = 17m

base [b] = 51m
