<span>The surface of this shape is called a rectangle.
</span><span>Opposing sides of the rectangle are of equal length .
</span><span>To fully fenced backyard you have to put a fence line the sides of the rectangle. The length of the fence will be equaled total sides of the rectangle.
</span>the sum of the sides of the rectangle = <span>perimeter of a rectangle
 2a   +   2b                                          = P

a = 12 1/2 yards
b =  5 1/2 yards

2* 12 1/2 yards + 2* 5 1/2 yards = 25yards + 11 yards = 36 yards

The perimeter of a rectangle is 16.6km, and its area is 13.42km2. Find its length and width. length : km width : km
Otrada [13]

Answer:

l=5.12 & w=2.62

Step by step explanation:

A=l×w

13.42=lw

w=13.42/l

p = 2(l + w) \\ 16.6 = 2(l +  \frac{13.42}{l} ) \\ 16.6 = 2( \frac{ {l}^{2}  + 13.42}{l}) \\ 16.6 = 2(l + 13.42) \\ 16.6 = 2l + 26.84 \\ 2l = 26.84 - 16.6 \\ 2l = 10.24 \\ l =  \frac{10.24}{2}  \\ l = 5.12km

Since you have found the value of the length you can find the value.of the width.

w =  \frac{13.42}{l}  \\ w =  \frac{13.42}{5.12}  \\ w = 2.62km
