Question

the base of an isosceles triangle is 16 cm.if it's perimeter is 36 cm,find it's area?​

Answer 1

Answer:

Step-by-step explanation:

Let the one side of the isosceles triangle be x

then we know that the 2 sides of isosceles traingle are equal so the 2nd side is also x

Then equation,

X+x+16 = 36

2x = 36 - 16

2x = 20

X = 20/2

X=10

The 1st side = 10 cm

2ndside = 10cm
