The area of a triangle is 7.5 square meters, and the area of a parallelogram with the same base and height is () the bottom of a parallelogram is 5 meters, and the height of a parallelogram is 5 meters

The area of a triangle is 7.5 square meters, and the area of a parallelogram with the same base and height is () the bottom of a parallelogram is 5 meters, and the height of a parallelogram is 5 meters

The area of a triangle is 7.5 square meters, the area of a parallelogram with the same base and height is (15 square meters), the bottom of a parallelogram is 5 meters, and the height of a parallelogram is 3 meters

If the bottom of a parallelogram is increased by 8m and the height remains unchanged, the area will be increased by 176 square meters. If the height is increased by 6m and the bottom remains unchanged
If the bottom of a parallelogram is increased by 8m and the height remains unchanged, the area will increase by 176 square meters. If the height is increased by 6m and the bottom remains unchanged, the area will increase by 96 square meters. What is the area of the original parallelogram?

Bottom = 176 △ 8 = 22m
Height = 96 △ 6 = 16M
Original area = 22 × 16 = 352m2

A parallelogram steel plate, the bottom is 3.8m, the height is 1.5m, calculate its area?

3.8 × 1.5 = 5.7 (M2), 5.7 × 39 = 222.3 (kg); a: its area is 5.7 m2, and the whole steel plate weighs 222.3 kg
