The area of the back yard is 216 square meters.
160 meters. Width = 30 Length = 50 W+W+L+L = perimeter or Width x 2 + Length x 2 = Perimeter. 50 + 50 +30 +30 = 160
8 meters and 4 meters
The perimeter would be 28 meters.
The perimeter is 42 metres.
Perimeter of rectangle = 2 x (length + width) = 2 x (1.6 + 0.8) = 2 x 2.4 = 4.8 meters
134 meters
12 meters
Width: 16 meters Length: 21 meters Check: 16+21+16+21 = 74 meters which is its perimeter
24 meters
Perimeter of a rectangle = twice (length + width), in this case 22 m.
The width of the rectangle is 13 meters. The perimeter of the rectangle is 50 meters, and its length is 12 meters. The 50 meters is 2 times the length plus 2 times the width. With a length of 12 meters, twice that is 24 meters. That leaves 50 meters - 24 meters for twice the width. And 50 - 24 = 26, which is twice the width. The 26 meters divided by 2 = 13 meters, which is the width of the rectangle.
