Since there are two of each side, there are two 9s and two 12s, so the perimiter is 2*12+2*9, which is 24+18, which is 42.
A rectangle with sides of 1cm and 6cm has an area of 6 cm2 and a perimeter of 14 cm. A rectangle with sides of 2cm and 3cm has the same area but its perimeter is 10 cm.
The rectangle has a length of 12 cm and a width of 3 cm.
It has 2 sides of 5 cm and 2 sides of 6 cm so the perimeter is 22 cm
If it's a 12 by 5 rectangle then the perimeter is: 12+5+12+5 = 34 cm
Perimeter of rectangle = 2 x ( L + W ) = 2 x 64 = 128 cm. or Perimeter of rectangle = 2L + 2W = 68 + 60 = 128 cm.
11 cm2 zero, when two opposite sides are 12 cm, and the rectangle is infinitely thin
Add up the lengts of all four sides.
The perimeter of a 12 cm x 3 cm rectangle is 2*(12+3) cm = 2*15 cm = 30 cm.The perimeter of a 12 cm x 3 cm rectangle is 2*(12+3) cm = 2*15 cm = 30 cm.The perimeter of a 12 cm x 3 cm rectangle is 2*(12+3) cm = 2*15 cm = 30 cm.The perimeter of a 12 cm x 3 cm rectangle is 2*(12+3) cm = 2*15 cm = 30 cm.
The answer is 12 cm.
12 cm
A rectangle with sides of 1cm and 6cm has an area of 6 cm2 and a perimeter of 14 cm. A rectangle with sides of 2cm and 3cm has the same area but its perimeter is 10 cm.
100 cm
The perimeter is the sum of the four sides. In this case, two sides have 14 cm each, and the other two sides have 5 cm eacn.
30 cm. 2 sides are 9 cm and 2 sides are 6 cm (2x9)+(2x6)=? 18+12=30
The rectangle has a length of 12 cm and a width of 3 cm.
It has 2 sides of 5 cm and 2 sides of 6 cm so the perimeter is 22 cm
Write an equation for the perimeter, and solve it. Remember that the perimeter is the sum of all four sides.
