Question

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

Answer 1

Answer:

this is your answer

Step-by-step explanation:

let the sides be a,b&c

let the side a & b are equal(a=b)

a:c = 1:3

a/c = 1/3

c = 3(a)..................(1)

ATQ:-

a+b+c=32

putting value of c from (1)

a+a+3a=32

5a =32

a=32/5

a=6.4

b=6.4

c=19.2
