Question

perimeter of an isoceles triangle is 252 cm. if the length of its unequal side is 72 cm, find the length of its equal sides.
​

Answer 1

Answer:

answer will be 90cm of each equal side.

Step-by-step explanation:

1.perimeter of any triangle= side+side+side =252m.{here}

2.one length=72cm.other sides=x as both side is equal

3.72cm+x+x=252m

4.2x=252cm-72cm as plus at RHS becomes minus at LHS

5.2x=180cm

6.x=180cm/2=90cm

Therefore each equal side of triangle=90 cm
