The length of the rectangle is increased to 56 meters, but the width remains unchanged. What is the area after expansion? The original length is 28 meters, and the area is 252 square meters

The length of the rectangle is increased to 56 meters, but the width remains unchanged. What is the area after expansion? The original length is 28 meters, and the area is 252 square meters

The length should be doubled and the area should be doubled to 504 square meters

The length of a rectangular green space is 28 meters and the area is 252 square meters. If the length is increased to 56 meters and the width remains unchanged, what is the area after expansion?

56 × (252 △ 28) = 56 × 9 = 504 (square meters) a: the expanded area is 504 square meters

The area of a rectangular green space is 252 square meters, and the length of one side is 18 meters. The width increases to 36 meters, and the length remains unchanged. What is the expanded area?

252 △ 18 = 14 (m) 14 ＜ 18, so 18 m is a rectangle, the expanded area is: 36 × 18 = 648 (M2) a: the expanded green area is 648 m2
