Question

Solve this problem please

Answer 1

Hi, Ptaverez1! :)

First we must length of an individual square; This can be achieved by using the formula for the area of a square:

`l^2`

`l=Length`

Lets input the information we already know:

`l^2=42.25`
Take square root.

`l=\sqrt42.25`

`l=6.5`

The length of an individual square tile is 6.5 ft.

Since they're are 9 tiles and the porch in a square, I can conclude that the measurements for the porch are 3 tiles by 3 tiles (as 3*3=9; using the formula for the area of a square.)

Since the length of the porch is 3 tiles, we must multiply the individual tiles piece length by 3:

`3*6.5`

`=19.5`

The formula for the perimeter of a square is:

`l*4`

`l=length`

Lets input the information we know:

`19.5*4`

`=78`

The perimeter of the porch is 78 feet²

Hope this helps.
