The length of the equal sides of the given quadrilateral comes to be 11 inches.

What is a quadrilateral?

A quadrilateral is a polygon with 4 sides.

Suppose the length of the three equal sides =x inch

Length of the fourth side =7 inches

So, the perimeter of the quadrilateral = x+x+x+7

The perimeter of the quadrilateral = 3x+7

Given that the perimeter of the quadrilateral = 40inches

3x+7=40

3x=33

x=11

So, the length of three equal sides = 11 inches

Therefore, the length of the equal sides of the given quadrilateral comes to be 11 inches.
