Evan is landscaping his backyard. The yard is shaped like a rectangle and measures 80 feet by 70 feet. He wants to spread topsoil evenly over the entire surface. One load of topsoil will cover 400 square feet, 4 inches deep. How many loads of dirt does Evan need in order to cover his entire yard?
What is the area of the yard?
Are you sure about that wolfe?
if i do BxH i get 5600 so then subtract the 400 and get 5200!
You need to cover 5600 square feet. Each load covers 400 square feet. divide 5600 by 400 to see how many loads are needed.
but my answer options are 14 16 18 20 ??
@wolfe you're right, we can divide by repeatedly subtract, but that's reserved for grade school where they have not yet learned division.
