Arectangular parking lot measures 80.0 m by 75.0 m. if the parking lot needs three sections that each measure 8.00 m by 8.00 m for tree plantings, how much area is left for parking spaces?

80 × 75 = 6,000. that means that the parking lot is 6,000 meters squared.
Now, find the area each tree planting section takes up: 8 × 8 = 64. But 64 meters squared only gives us the space of one tree space. so multiply 64 × 3, which gives you 192.
Now that we have the total space that the trees take up, which is 192 meters squared, we can subtract that from the total parking lot space.
6,000 minus 192 equals 5,808.
5,808 square meters are left for parking spots.
