Question

Help please,

Each side of a square has a length of 5x. Use your area expression to find the area of the square when x = 2.2 centimeters. Show your work.

Answer 1

A=l*w or in the case of a square
`l^(2)`

So your length is 5x so plug that into your equation
A=
`(5x)^(2)` or
`25 x^(2)`

Then plug in your 2.2
25*
`2.2^(2)` = 25*4.84 = 121

Hope that helps

Answer 2

5x2.2 = 11
11x2 = 22
Area=22
