Question

The base of an isoscles triangle is 16cm and its area is 48cm square find its perimeter of triangle

Answer 1

Answer:

Perimeter 36cm

Hope this helps.

Step-by-step explanation:

Area = (half base) × height

=> height = Area / (half base) = 48 / 8 = 6

By Pythagoras' Theorem:

(slant side)² = (half base)² + height² = 8² + 6² = 64 + 36 = 100

=> slant side = 10

Perimeter = base + (one slant side) + (other slant side)

= 16 + 10 + 10

= 36
