Find the perimeter of 7cm and 8cm

20

Try a rectangle with dimensions of 6 cm and 7 cm, and see what you get.

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

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

The perimeter of a 5 by 7 rectangle is 24.

7 x 19 cm

Perimeter = 7+7+4+4 = 22 cm

Perimeter =7+7+10+10 = 34 cm

length 18 width 7

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

20 x 2 = 4007 x 2 = 1440 + 14 = 54cmSo the perimeter is 54cm

Length + width = half of perimeter, ie 18 cm. 18 - 4 = 14, 14/2 = 7 so sides are 7 and 11 cm and area = 77sq cm

Suppose the width is W cm. Then the length is 3W cm. THerefore, the perimeter is 2*(3W + W) = 8W = 56 So W = 7 cm.

It can be infinitely large. Consider a rectangle of length A cm where A â‰¥ 7 cm. And let its width be B = 49/A cm. Then its area is always A*B cm2 = A*49/A cm2 = 49 cm2. Let A = 10 cm, B = 4.9 cm so perimeter = 29.8 cm or A = 100 cm, B = 0.49 cm, perimeter = 200.98 cm or A = 1000 cm, B = 0.049 cm, perimeter = 2000.98 cm By making the rectangle infinitesimally thin and infinitely long, its perimeter can be increased without limit.

The perimeter of this rectangle is 30 inches.

The perimeter is 7 cm

Area = 35 cm2 and one side = 5 cm => other side = 7 cm So perimeter = 2(5 + 7) = 2*12 = 24 cm

Perimeter of rectangle: 2*(7+6) = 26 m

60 and 62

The length is 4 cm, the width is 26 cm.

7 cm x 3 sides = 21 cm perimeter.
