If the length of a rectangle is reduced by 1.5 meters, or the width is reduced by 1.2 meters, the area will be reduced by 6 square meters I'll give you extra points tonight. I'm not waiting
If the length is reduced by 1.5 meters, the area is reduced by 6, and the width of the original rectangle is 6 / 1.5 = 4;
If the width is reduced by 1.2 meters, the area is reduced by 6, and the length of the original rectangle is 6 / 1.2 = 5;
So the area of rectangle is 4 * 5 = 20
If the length of a rectangle is reduced by 1.5 meters or the width by 1.2 meters, its area will be reduced by 6 square meters. What is the area of this rectangle______ ．
(6 / 1.2) × (6 / 1.5) = 5 × 4 = 20 (square centimeter); answer: the area of this rectangle is 20 square centimeter. So the answer is: 20 square centimeter
For a trapezoid, the ratio of the upper bottom to the lower bottom is 4:9. If the lower bottom is reduced by 15 cm, it will become a square. The area ratio of this square to that of the original trapezoid is 4:9______ ．
The area of the square is 12 × 12 = 144 (square centimeter); the area of the trapezoid is [(4 + 9) × 3] × 12 / 2, = 39 × 12 / 2 = 468 / 2, = 234 (square centimeter). The area ratio of the square to the original trapezoid is 144:234 = 8:13 The area ratio of the square to the original trapezoid is 8:13
If the length of a rectangle is reduced by 1.5 meters or the width by 1.2 meters, its area will be reduced by 6 square meters. What is the area of this rectangle______ ．
(6 / 1.2) × (6 / 1.5) = 5 × 4 = 20 (square centimeter); answer: the area of this rectangle is 20 square centimeter. So the answer is: 20 square centimeter
If the length of a rectangle remains unchanged and the width increases by 2 meters, the area will increase by 12 square meters; if the width remains unchanged and the length increases by 3 meters, the area will also increase by 12 square meters______ Square meters
A: the original area of this rectangle is 24 square meters. So the answer is: 24
If the length of a rectangle remains unchanged and the width increases by 2 meters, the area will increase by 12 square meters; if the width remains unchanged and the length increases by 3 meters, the area will also increase by 12 square meters______ Square meters
A: the original area of this rectangle is 24 square meters. So the answer is: 24
If the length of a rectangle remains unchanged and the width increases by 2 meters, the area will increase by 12 square meters; if the width remains unchanged and the length increases by 3 meters, the area will also increase by 12 square meters______ Square meters
A: the original area of this rectangle is 24 square meters. So the answer is: 24
If the length of a rectangle remains unchanged and the width increases by 2 meters, the area will increase by 12 square meters; if the width remains unchanged and the length increases by 3 meters, the area will also increase by 12 square meters______ Square meters
A: the original area of this rectangle is 24 square meters. So the answer is: 24
A 200 square meter green space, 8 meters long, length unchanged, width increased to 24 meters, after the expansion of the green area is how much
200 / 8 = 25m
25 + 24 = 49m
49x8 = 392 M2
There is something wrong with this question. Is it increased or increased to? If it is increased to, the area should be reduced
