Question

the perimeter of an isosceles triangle is 38m. if its base is 10 cm, find the length of each of equal sides

Answer 1

P=38m
b=10cm
Let the side be x so other side is also x.
P=x+x+b
38=x+x+10
28=2x
x=14

The length of each equal side is 14cm.

Answer 2

Step-by-step explanation:

Perimeter of an isoceles ∆ = 2a + b

=> 38 = 2a + 10

=> 38-10 = 2a

=> 2a = 28

=> a = 14 ans.
