A 1.8 m wide path is built around a rectangular pool 20 m long and 8.7 m wide. What is the distance around the outside of (a) the pool? (b) the path?
Plz answer with detailed steps
Answers
Answer:
a) 57.4 m
b) 71.8 m
Step-by-step explanation:
a) This first part is a perimeter problem, so you add up all the sides of the pool. The pool is a rectangle, so the 2 lengths are 20 m each and the 2 widths are 8.7 m each.
20 + 20 + 8.7 + 8.7 = 57.4
b) To find the distance around the path, you need to add to your original length and width. First, start with the length. You add 1.8 to each end of the length, like so:
20 + 1.8 + 1.8 = 23.6
That is your new length, now you have to find the new width. You do the same thing, add 1.8 to each end of the width, like so:
8.7 + 1.8 + 1.8 = 12.3
Now that you have the new length and width that include the pathway, you do the same thing as in part a to find the perimeter (or distance around the path)
23.6 + 23.6 + 12.3 + 12.3 = 71.8
Answer:(a) 57.4m is the answer
