Question

the preimeter of an iscscles triangle is 32 cm . the ratio of the equal side to its base is 3:2 find the area of the triangle​

Answer 1

Step-by-step explanation:

let the common ratio be x

then ratio is 2x:3x

given base is 2x

also given its an isosceles triangle

2x+3x+3x=32

8x=32

x=4

the sides are 8,12,12

semi perimeter=8+12+12/2

=32/2

=16

area=√16(16-8)(16-12)(16-12)

=√16(8)(4)(4)

=√16*16*8

=16√8 units
