If a square is enlarged by 3:1, its area will be expanded by 3 times______ (judge right or wrong)


When a square is enlarged by a ratio of 3:1, its perimeter will be increased by 3 times and its area will be increased by 9 times



A rectangle can be divided equally into six squares with 3 / 4 sides. Find the area and perimeter of the rectangle,


Area = 3 / 4 * 3 / 4 * 6 = 27 / 8 square
Zhou Chang has two answers. The first is 3 / 4 * 14 = 21 / 2 (?), the second is 3 / 4 * 10 = 15 / 2 (?)



A rectangle can be equally divided into six squares with three fifths of the side length
Come on, it's before nine o'clock! I'll add ten more after answering!


Because 6 = 1x6 = 2x3, there are two kinds of answers: length is 3 / 5x6 = 18 / 5 decimeters, width is 3 / 5 decimeters, perimeter is (18 / 5 + 3 / 5) x2 = 42 / 5 decimeters, 18 / 5x3 / 5 = 54 / 25 square decimeters, length is 3 / 5x3 = 9 / 5 decimeters, width is 3 / 5x2 = 6 / 5 decimeters, perimeter is (9 / 5 + 6 / 5) x2 = 6 decimeters, area is 9 / 5x6 / 5 = 54 /



A rectangle can be evenly divided into six squares with sides of 3 / 4 meters. Find the perimeter of the rectangle


It could be six squares in a row
It can also be three squares long and two squares wide
The perimeter of the first type is 3 / 4x (6x2 + 1x2) = 3 / 4x14 = 21 / 2m
The perimeter of the second type is 3 / 4x (3x2 + 2x2) = 3 / 4x10 = 15 / 2m



A rectangular flower bed can be divided into 6 squares with a side length of 3 / 4 meters. Calculate the area of this rectangle!


6 × (3 / 4) square = 27 / 8 square meters



A rectangle can be divided into six squares whose sides are three fourths of a meter. Find the area and perimeter of the rectangle
A rectangle can be divided into six squares whose sides are three fourths of a meter


There are two cases
The first one is divided into a line-up square, the length of the rectangle is 3 / 4 × 6 = 9 / 2m, and the width is 3 / 4m
The perimeter is (9 / 2 + 3 / 4) × 2 = 10.5m
The second one is divided into two rows, three in each row, with length = 3 / 4 × 3 = 9 / 4m and width = 3 / 4 × 2 = 3 / 2m
Perimeter = (9 / 4 + 3 / 2) × 2 = 7.5m
In either case, the area is equal: 3 / 4 × 3 / 4 × 6 = 27 / 8 square meters
Please take the answer and support me



A rectangle can be equally divided into six squares with sides of 34 meters


Because the length of the rectangle is: 34 × 3 = 94 (meters), the width is: 34 × 2 = 32 (meters), the area of the rectangle is: 94 × 32 = 278 (square meters), the perimeter of the rectangle is: (94 + 32) × 2, = 154 × 2, = 7.5 (meters), a: the area of the rectangle is 278 square meters, the perimeter is 7.5 meters



If one side of a rectangle is equal to 3m + 2n and the other side is M-N smaller than it, the perimeter of the rectangle is______ .


According to the meaning of the title, the other side is 3M + 2n - (m-n) = 2m + 3N, so the perimeter of the rectangle is 2 (3m + 2n + 2m + 3n) = 10 (M + n)



One side of a rectangle is 3M + 2n, and the other side is M-N larger than it


[(3m+2n)+(3m+2n+m-n)]*2
=(7m+3n)*2
=14m+6n



If one side of a rectangle is equal to 3m + 2n and the other side is M-N smaller than it, the perimeter of the rectangle is______ .


According to the meaning of the title, the other side is 3M + 2n - (m-n) = 2m + 3N, so the perimeter of the rectangle is 2 (3m + 2n + 2m + 3n) = 10 (M + n)
