I am guessing this is a homework question so I will explain how to get the answer rather than just answer it. If the length is 10 meters then the 2 sides of the length equal 10 meters. If you subtract that from 24 meters you are left with 14 meters. What is the width? Remember there are 2 sides to the width.
66metres
12 meters
Width: 16 meters Length: 21 meters Check: 16+21+16+21 = 74 meters which is its perimeter
The perimeter is 42 metres.
24 meters
66metres
12 meters
Perimeter of rectangle = 2 x (length + width) = 2 x (1.6 + 0.8) = 2 x 2.4 = 4.8 meters
Width: 16 meters Length: 21 meters Check: 16+21+16+21 = 74 meters which is its perimeter
The perimeter is 42 metres.
length is 3 and width is 9
134 meters
width=5 length=12
24 meters
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.
It depends what shape the section is, ie what the length and width are. If you can specify this I can work out the perimeter length.
The length is 10 meters and the width is 5 meters
