Question

A silk scarf is in the shape of an isosceles triangle.the two equal sides of the scarf are 8cm more than twice the third side.if the perimeter of the scarf is 71cm, find the lengths of the sides of the scarf.

Answer 1

Step-by-step explanation:

let the third side be x

According to question _

first and second side = 2x+8

given_ perimeter =71 cm .

x+2x+8+2x+8=71

5x+16=71

5x=71-16

5x=55

x=55/5

x=11

first side = 2x+8=2(11)+8=30cm

Second side=2x+8=30cm

third side=x=11cm

Answer 2

Answer:

let the third side be x

ATQ

first and second side=2x+8

given perimeter=71cm

x+2x+8+2x+8=71

5x+16=71

5x=71-16

5x=55

x=11

First side =2x+8

=30cm

second side=2x+8=30

third side=x

x=11
