There are 4 sides to a rectangle and there are 2 sets of parallel sides equal in length. To calculate the perimeter you need to do 2(r+3) + 2(2r+9) which equals 6r+24. Hope this helps.

Lance used two gallons of paint to pain 785 square feet. How many gallons will he need to purchase to cover 2,500 square feet?

Digiron [165]

Answer:

7 gallon

Step-by-step explanation:

Divide the space that needs paints by how much space has been painted

2500/785 = 3.18

Then double that because it takes 2 gallons to paint every 785 square feet

3.18 x 2 = 6.36

You would need 6.36 gallons of paint, which would round up to 7 because you cannot buy 0.36 of a gallon
