The area of a square is calculated using the formula s², where s is a side length of the square.
If we plug in our known quantities, we get the equation:
121 = s²
In order to get rid of the square, we must perform the inverse operation, which is to square root.
√121 = s
11 = s
Therefore, a side length of the square would be A. 11 in.
The perimeter of the rectangle ABCD:
P = 2AD + 2AB
We have AD = 4z and AB = 5z + 2 and perimeter = 220 units. Substitute:
2(4z) + 2(5z + 2) = 220 <em>use distributive property</em>
8z + (2)(5z) + (2)(2) = 220
8z + 10z + 4 = 220 <em>subtract 4 from both sides</em>
18z = 216 <em>divide both sides by 18</em>
z = 12 units
Substitute to AD:
AD = 4(12) = 48
<h3>Answer: AD = 48 units.</h3>

If you mean "Who's" good at area of rectangles then yes I am.... It's just the base of the rectangle times the height and that will give you the area.
