Question

The base of an isosceles triangle is 16 m If its perimeter is 36 cm, find its area.​

Answer 1

Answer:

The base of an isosceles triangle is 16 m If its perimeter is 36 cm, find its area.

= 48 sq cm

Answer 2

Answer:

48 sq cm

Step-by-step explanation:

since perimeter =36and base is 16. Each side is 10 (10+10+16=36 perimeter)

In an isosceles triangle, the perpendicular from the 3rd point of the triangle on the base sivides the base so half of base and height and one side becomes a right angle

now using pythagoras therom

h^2=side^2 -(base/2)^2=100-64=36

h=6

area of triangle=1/2*b*h=1/2* 16 *6=48sq cm
