Problema Solution
A square and a rectangle have the same perimiters. the length of a side of the sqaure is 4x-1. the length of the rectangle is 2x+1 and the width is x+2. write and solve an equation to find x
Answer provided by our tutors
the length of a side of the square is 4x-1
the perimeter of the square is 4*(4x - 1)
the length of the rectangle is 2x+1 and the width is x+2
the perimeter of the rectangle is 2(2x + 1 + x + 2)
a square and a rectangle have the same perimeters
4*(4x - 1) = 2(2x + 1 + x + 2)
by solving we find
x = 1
