Question

find the base of an isosceles triangle whose area is 60 square cm and the length of equal side is 13 cm​

Answer 1

Answer:

34cm

Step-by-step explanation:

as it is given=13*2=26

60-26=34cm

Answer 2

Answer:

let base x, altitude p and area A

area=1/2(x*p)=60

p=120/x

now, by applying theorem

(x/2)2 + (120/x)2 = 13

solving this equation ,we get;

x=24 , x=10.
