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

  • MATH -

    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.
