Ah well this would look like 2(30) + 30 = 90 aka 2L + W = 90
The absolute value of a number is however many places a number is away from 0 on a number line.
a. |-15| + |-26|
15 + 26
41
b. -|-40|
-40
c. |0.5| + |-1 1/2|
0.5 + 1 1/2
0.5 = 1/2
1/2 + 1 1/2
2
The area would be 36 each side is 6 inches therefore you would multiply 6 by 6 to find the area
