let x=length of rectangle
let y=width of rectangle
x=y+5
2x+2y=40
2(y+5)+2y=40
2y+10+2y=40
4y+10=40
4y=30
4y=7.5
x=7.5+5
x=12.5
AREA:
12.5 x 7.5 = 93.75 YARDS

What is the area of a rectangle with a perimeter of 48 and a length of 5?
A rectangle with a perimeter of 48 and 1 side equal to 5 would have its other sides lengths of 5, 19, 19. Such a rectangle would have an area of 95 sq/m. Your question is somewhat strange, as the "length" of a rectangle generally refers to the longer side - in this case the length would be 19 and the width 5.
The length of a rectangle is 7 meters longer than the width what is the width of this rectangle if its perimeter is equal to 26 meters?
L + W = P/2 = 13. 13 - 7 = 6, 6/2 = 3 which is the width, making the length 10.
If a rectangle has a perimeter of 46 and the length is 11m longer than the width what is the width?
if the perimeter is 46m, then side + length = 23 so we need two values, when added together are 23, with a difference of 11 6 + 17 = 23, (and have a difference of 11) therefore the length = 17m, width = 6m

What is the perimeter of 7cm by 6cm?
Assuming that this is a rectangle, you know that the length (longer side) would be 7cm, and the width (shorter side) would be 6cm. The formula for perimeter is, 2(length) + 2(width) = Perimeter Now we can plug in our numbers, 2(7cm) + 2(6cm) = 14cm + 12cm = 26cm The perimeter would be 26cm, assuming that this is a rectangle ^^

a rectangle as a longer side because there's 48 inches for a rectangle but there's only 45 inches for a triangle. a rectangle as a longer side because there's 48 inches for a rectangle but there's only 45 inches for a triangle.
