Question

The perimeter is 20ft. Write an equation and use it to find the value of X.

Answer 1

To calculate the value of x in the diagram below:

The perimeter of a a square =

$\begin{gathered} P\text{ = }4l \\ \text{Where P = perimet}er \\ l\text{ = length} \end{gathered}$$\begin{gathered} \text{Length = x ft} \\ P\text{erimeter = 20 ft} \\ P=\text{ 4l} \\ P=4x \\ 20\text{ = 4x} \\ x=\frac{20}{4} \\ x=5ft \end{gathered}$

Hence the value of x = 5ft
