Perimeter =7+7+10+10 = 34 cm
The perimeter and area don't depend on each other. Knowing one doesn't tell you the other. -- A circle with perimeter (circumference) of 20 cm has area of 31.83 cm2. -- A square with perimeter of 20 cm has area of 25 cm2 . -- A (9 x 1) rectangle has perimeter of 20 cm and area of 9 cm2 . -- A (8 x 2) rectangle has perimeter of 20 cm and area of 16 cm2 . -- A (7 x 3) rectangle has perimeter of 20 cm and area of 21 cm2 . -- A (6 x 4) rectangle has perimeter of 20 cm and area of 24 cm2 .
Let's denote the width of the rectangle as "w" and the length as "3w". The perimeter of a rectangle is calculated by adding all four sides, so in this case it would be 2w + 2(3w) = 56. Simplifying the equation gives 8w = 56, and thus the width of the rectangle would be w = 7 cm.
60 and 62
The perimeter is 7 cm
It is: 7+8+12 = 27 cm
width = (x + 4) cm length = [(x + 4) + (x + 7)] cm Rectangle Perimeter = 2[(x + 4) + (x + 4 + x + 7)] cm Rectangle Perimeter = 2[(x + x + x) + (4 + 4 + 7)] cm Rectangle Perimeter = 2(3x + 15) cm Rectangle Perimeter = (6x + 30) cm
Try a rectangle with dimensions of 6 cm and 7 cm, and see what you get.

sum of sides is perimeter:14+14+7+7 = 42 cm
i don't know what length of rectangle is 7 cm longer than the width the perimeter of the rectangle is 46 cm .what is the length of the of the rectangle ?
Assuming the object is a rectangle, the perimeter is (2 x 7cm) + (2 x 10 cm) = 34cm
7 x 19 cm
Perimeter = 7+7+4+4 = 22 cm
Perimeter =7+7+10+10 = 34 cm
The perimeter and area don't depend on each other.

Length is 11 and width is 7 and so 11 times 7 = 77 square cm
