Question

the perimeter of an isosceles triangle is 28cm.the unequal is 10cm.find the length of each equal side​

Answer 1

Answer:

9 cm

Step-by-step explanation:

Let the same sides measure x cm each.

Unequal side=10 cm

So, perimeter=x+x+10 cm

Given,

Perimeter=28 cm

=>x+x+10cm=28cm

=>2x=28-10cm

=>2x=18cm

=>x=9 cm

Thus, each equal side measures 9 cm.
