Please answer i need help

Answer 1

Area = 144 units^{2}

Explanation:

Since the sides of a square are equal, the perimeter is:

`perimeter = 4*length`

Substituting perimeter = 48 and
`length = 5x+2`, then:

`48 = 4*(5x+2)`

By dividing on both sides:

`(48)/(4)  = (4*(5x+2))/(4)`

`12  = 5x+2`

Rearranging:

`12 -2 = 5x+2-2`

`10 = 5x`

`x = 2`

To calculate the area, we need to calculate the length:

`length = 5x+2 = 5*2+2 = 12`

The formula for Area is:

`Area = Length^(2)`

`Area = 12^(2) = 144 units^(2)`
