Question

Perimeter of an isosceles triangle is 252 cm.
If the length of its unequal side is 72 cm,
find the length of its equal sides.​

Answer 1

Answer :90

Eplanation :Let the equal side be x

perimeter of triangle =252 cm

x + x + unequal side = 252cm

2x + 72 cm = 252 cm

2x = 180 cm

x =180/2

x = 90

Answer 2

Answer:

perimeter of an isosceles triangle - 252 cm .

it's one unequal side length is - 72 cm

Let a =x , b=x ,c=72

a+b+c=252 cm

x+x+72=252 cm

2x+72=252 cm

2x=252-72 cm

2x=180 cm

x=180/2 cm

x= 90 cm
