Answer:48.6
we know that
You can paint 75 square feet of a surface every 45 minutes
so
using proportion
Find out how long it takes you to paint a surface area of 81 square feet
45(81)/75=48.6
hope this helped and I hope you get a correct answer :D
Area of a square is its side length squared...
A=s^2 solving for s...
s=√A
The perimeter of a square is 4 times its side length...
P=4s, and since s=√A
P=4√A, and we are told that A=100 in^2 so
P=4√100
P=4*10
P=40 in
