Question

Three sides of a quadrilateral are of the same length $q$.

The length of the fourth side is $7$ $inches$.

The perimeter of the quadrilateral is $40$ $inches$.

What is the length of equal side?

Answer 1

Solve for the length of the equal side of Quadrilateral:

Given that,

Three sides of a quadrilateral are the same length $q$

The fourth side is $7$ $inches$

Perimeter of the quadrilateral is $40$ $inches$.

$\therefore$Perimeter of quadrilateral $=40$
$\Rightarrow$ $3q+7=40$

$\Rightarrow$ $3q=40-7$

$\Rightarrow$ $q=\frac{33}{3}$

$\Rightarrow$ $q=11inches$

Hence, the length of each of three equal sides of the Quadrilateral is $11$$inches$
