Question

The length of each of the legs of an isoceles triangle is 5 times the length of the base. The perimeter of the triangle is 33 m. Find the length of one leg.

Answer 1

What the person said above me

Answer 2

Explanation:

Let's call the length of the base of the triangle b. The two other sides are both the same length. From the problem, we know their lengths are both 5b. We also know the sum of all these lengths is 33m. So,

33m = 5b + 5b + b

33m = 11b

3m = b

Therefore, the base of the triangle is 3m and the two other sides are five times longer at 15m.

hope this helps :)
