1. A residental lot has shape of a parallelogram. Its base measures 20 meters. The distance between the 12 parallel sides is 8 meters. What is the area of the lot?
2. A triangular landscape has a base of 24 meters and a height of 12 meters. Find its area.
3. A trapezoidal lawn has an upper base of 16 meters and a lower base is 30 meters. The distance between the parallel bases is 10 meters. If the lawn is to be planted with Bermuda grass, how many square meters Bermuda grass will be needed?

1. To find the area of the parallelogram-shaped residential lot, use the formula: Area = base x height, where the height is the distance between the parallel sides.
Area = 20 meters x 8 meters
Area = 160 square meters
Therefore, the area of the residential lot is 160 square meters.
2. To find the area of the triangular landscape, use the formula: Area = 1/2 x base x height.
Area = 1/2 x 24 meters x 12 meters
Area = 144 square meters
Therefore, the area of the triangular landscape is 144 square meters.
3. To find the area of the trapezoidal lawn, use the formula: Area = 1/2 x (upper base + lower base) x height.
Area = 1/2 x (16 meters + 30 meters) x 10 meters
Area = 230 square meters
Therefore, 230 square meters of Bermuda grass will be needed to plant the trapezoidal lawn.
