Question

the base and perimeter of an isosceles triangle are 7/2cm and 12cm. find the length of each of its equal sides​

Answer 1

Step-by-step explanation:

we know that perimeter of the triangle = sum of all the sides of the triangle

let the equa. sides of the isosceles triangle be x

therefore , perimeter = x+x+7/2 (one side is given)

2x+7/2=12 => 2x=12-7/2

= 2x=17/2 therefore x = 17/4 cm = 4.25 cm
