To calculate the perimeter of a rectangle one adds twice the width and twice the length... in this case (2 x 3 metres) + (2 x 7 metres) = 6 metres + 14 metres = 20 metres.
Perimeter of a rectangle = twice (length + width), in this case 22 m.
22 meters.
The perimeter is 42 metres.
Perimeter: 7+3+7+3 = 20 inches Area: 7 times 3 = 21 square inches
A rectangle 10.5 x 3 will have a perimeter of 27 in.
Perimeter of a rectangle = twice (length + width), in this case 22 m.
22 meters.
The perimeter is 42 metres.
1317 metres
Perimeter: 7+3+7+3 = 20 inches Area: 7 times 3 = 21 square inches
im not sure if this is right, but i think it should be 26 meters
A rectangle 10.5 x 3 will have a perimeter of 27 in.
L + W = P/2 = 13. 13 - 7 = 6, 6/2 = 3 which is the width, making the length 10.
28 meters It would be a square because A = L x W so 49 = 7 x W and the width is 7. Its perimeter is 4*7 = 28 meters.
3+3+7+7 = 20 inches
To find the perimeter of a polygon, just add the length of all the sides. In this case, the four sides of the rectangle.
The perimeter of this rectangle is 30 inches.
