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
length is 3 and width is 9
The perimeter is 42 metres.
134 meters
width=5 length=12
24 meters
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 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.
The length is 10 meters and the width is 5 meters
