Problema Solution

a triangles perimeter is equal to the perimeter of a square. the triangle has a side that is 4x-3. another side is 3x and the other is 16. the square has two sides that are 2x. what is the length of a side of the square.

Answer provided by our tutors

the triangle has a side that is 4x-3. another side is 3x and the other is 16 thus the perimeter of the triangle is


P1 = 4x - 3 + 3x + 16 = 7x + 13


the square has two sides that are 2x thus the perimeter of the square is


P2 = 4*2x = 8x


a triangles perimeter is equal to the perimeter of a square


P1 = P2


7x + 13 = 8x


by solving we find


x = 13
