Multiply 20 by 5 and you get 100, please tell if this is what you wanted!
Formula for Perimeter of Rectangle:
P = 2(L + W)
Plug in 160:
160 = 2(L + W)
L = 4W
<span>So we can plug in '4W' for 'L' in the first equation.</span>
<span>160 = 2(L + W)
160 = 2(4W + W)
Combine like terms:
160 = 2(5W)
160 = 10W
Divide 10 to both sides:
W = 16
Now we can plug this back into any of the two equations to find the length.
L = 4W
L = 4(16)
L = 64
So the width is 16, and the length is 64.</span>

I need help with the same thing-
Step-by-step explanation:
Answer: b)
Step-by-step explanation:
You can rule out A) and C), because you have to find area (no adding.)
To do this problem, you can individually multiply the estimated hieght and
width by 3 and then multiply together.
This is because there are 3 walls that each are 9 3/4 tall and 14 1/4 wide. To find total height and width, multiply by 3. Then find total area (lxw)
9 3/4 rounds to 10
14 1/4 rounds to 14
= 3 (10) x 3 (14)
D) is incorrect because you have to multiply each number by 3. (Or you can multiply by 6)
It is B)
