If a rectangular lawn is 8 times longer and 2 times wider, its area is 256 square meters. How many meters is the original area of this lawn?
If the length is expanded by 8 times and the width is expanded by 2 times, the area will be expanded by 2 * 8 = 16 times
256 △ 16 = 16 (M2)
As shown in the figure, the large side is 4cm long, and the small side is 3cm long. Calculate the area of the shadow part

The length of a rectangle is 36 meters, which is three times the width. What is the area and perimeter of the rectangle?
Width: 36 / 3 = 12m
Area: 12 * 36 = 432
Perimeter: 12 + 12 + 36 + 36 = 96 (m)
