Question

Each leg of an isosceles triangle is 4 meters longer than the base.the perimeter of the triangle is 26meters. Find the lengths of the sides

Answer 1

Because the triangle is isosceles, we know that it has 2 equal sides, which are the 2 legs. We can create an equation with the given information:

26 = 2(b + 4) + b

26 = 3b + 8

18 = 3b

b = 6

If the base is 6, add 4 to get 10.

base = 6 meters

leg = 10 meters

other leg = 10 meters

Hope this helps! :)
