Question

the perimeter of an isosceles triangle is 32cm the ratio of the equal side to its base is 3 ratio 2 find the area of the triangle

Answer 1

let the sides are in the ratio of 3:3:2
3x+ 3x+2x =32
8x=32
x=4
sides are = 12,12,8
s = 32/2 =16
area =
$\sqrt{16 \times 12 \times 12 \times 8}$
96√2
