AND
THE dimensions of rectangular parking lot are 330ft by 480ft
What is the area of the parking lot in square yards?

Answer 1

We need to find the price of one item.

50 for $1.25 = 1.25 / 50 = $0.025 each
100 for 2.25 = 2.25 / 100 = 0.0225 each

Do the others the same way. What do you find is the best price?

330ft = 330/3 = 110 yards
480 ft = 480/3 = 160 yards

A = L * W
A = ?

You find the area of a rectangle by multiplying the length times the width.

In this problem, I converted feet to yards. Multiply the length times the width.
