Question

find the area of an isosceles right triangle whose equal side are 15cm each

Answer 1

Given that,

Base = 15 cm

Perpendicular = 15 cm


Area = Base ×Perpendicular /2

= 15 * 15 /2

= 225/ 2

= 112.5 cm^2

Answer 2

area of triangle=1/2 x base x height
                        =1/2 x 15 x 15
                        =1/2 x 225
                       =112.5cm²
