Question

the area of an isosceles triangle is 60 square centimetres the length of each of the equal sides is 13 cm find its base
solve according to quadratic equations​

Answer 1

Answer:

X= 120/3

Step-by-step explanation:

area= 60 cm.sq

Altitude = 13 cm

Base = x

Area of a triangle = 1/2(A×B)

A.T.Q

1/2(13×X)=60

13×X=60×2

13×X=120

X=120/13
