The length of each side of the square is; 20.5cm

Squares and equal sides

Since, all sides of a square have equal lengths;

  • We can assume that the the sides given are equal so that we have;

7x +3 = 5x +8

2x = 8 -3

2x = 5

x = 5/2

x = 2.5

By substituting x into either of the expressions! we have;

  • 7x + 3

  • 7(2.5) + 3 = 17.5 + 3

  • = 20.5
