Question

find the base of a triangle whose area is 220cm2 and height is 11cm.

Answer 1

Heya Frnd........☺

Ar. of ∆ = ½ * base(b) * height(h)

=> 220 = ½ * b * 11

Therefore ,

b = 220 * 2 / 11

b = 40 cm..............ANS

Answer 2

area of triangle= 1/2*base*h
220= 1/2*11*b
220= 5.5*b
220/5.5= b
b= 40 cm^2
