A teacher runs a total of 48 city blocks in a rectangular pattern. If the width of the run is 3x and the length of the run is 5x
+ 4, what is the perimeter of the path the teacher runs? all you have to do is a equation don't solve it :)
1 answer:
Answer:
P = 16x + 8
Step-by-step explanation:
Perimeter of a rectangle
= 2(L + W)
Given
L = 5x + 4 and
W = 3x
Therefore
Perimeter = 2(5x + 4 + 3x)
Rearrange the expression
P = 2(5x + 3x + 4)
P = 2(8x + 4)
Now expand the bracket
P = 2 x 8x + 2 x 4
P = 16x + 8
