Question

find the base of a triangle whose area is 132 cm sq and altitude is 22cm

Answer 1

Given:-

Area of triangle = 132 cm²
Altitude = 22 cm


Let b be the base and h be the altitude of triangle.

Area of triangle = 1/2*b*h
132 = 1/2*b*22
b = 132*2/22
b = 12 cm Ans.

Ans.) The base of a triangle is 12 cm.

Answer 2

Area of triangle=132 cm^2
Altitude=22cm
Ar of triangle= 1/2*b*h
132 = 1/2* b*22
b= 12cm
Hence,the base of ther triangle is 12cm
