The Base of the Triangle, b = ?

The Height of the triangle, h = 11 cm

The Area of the triangle, A = 220 cm^2

We know that ,

$area \: of \: triangle \: = \frac{1}{2} \times b \times h$

From this ,,,

Area , A = 1/2 × b × 11

220 = 11b / 2

11b = 220 × 2

11b = 440

b = 440/11

b = 40 cm

The Base of triangle, b is 40 cm
