If the height of a triangle is 5 cm, and its area is 40 sq. cms, then its base is ………….. cms. 

A) 16 

B) 18 

C) 20

D) 14

Answer 1

Correct option is A) 16

Let base of the triangle be x cm.

Given h = 5 cm and Area of triangle = 40cm²

⇒ 1/2 x base x height = 40

⇒ base = \(\frac{40\times2}{height}\) = 80/5 = 16 cm
