Answer: Perimeter = 38</h3>
=============================================
Work Shown:
A = area of rectangle = 88
W = width = 11
L = unknown length
A = L*W
88 = L*11
11L = 88
L = 88/11 ... divide both sides by 11
L = 8
The length is 8
----------
P = perimeter of rectangle
P = 2L+2W
P = 2(L+W)
P = 2(8+11)
P = 2(19)
P = 38
Answer:
210 blue lockers
Step-by-step explanation:
5 x b 7 x 150
5b=210
5b ÷ 5 = 210 ÷ 5
b = 210
210 + 150 = 360 (there adrenaline a total of 360 lockers in the school)
I think the answer is A. 40
