Question

The perimeter of a square dollhouse is 80 inches how long is each side

Answer 1

The Square has equall sides thus if we suppose that square has a side which is x inches then the Perimeter is :

`perimeter = 4 * x`

Thus

`80 = 4 * x`

Divide both sides by 4

`(80)/(4) = (4x)/(4) \\`

`20 = x`

`x = 20`

Thus each side has a value of 20 inches .
