Answer:
Length = 13
Width = 9
Step-by-step explanation:
The equation to find the perimeter is 2l+2w=44. The second equation is 2w-5=l since the length is 5 less than double the width.
2l+2w=44,2w-5=l (write equations)
use the equation for length, the second equation, and subtitute it into the first equation's l. Since all l is the same and 2w-5 is equal to l, we can use that equation for the l in 2l+2w=p
2(2w-5)+2w=44 (subtitute)
4w-10+2w=44
6w-10=44 (simplify)
6w=54 (add 10 to both sides)
w=9
use the width to find the length by plugging it into any original equation
2w-5=l
2(9)-5=l
18-5=l
13=l
Answer:
The length is 13.
The width is 9.
Step-by-step explanation:
length = x
width = w
1) x = 2w - 5
2) 44 = 2x + 2w
3) 44 = 2(2w - 5) + 2w
4) 44 = 4w - 10 + 2w
5) 44 = 6w - 10
6) 54 = 6w
7) w = 9
8) x = 2(9) - 5
9) x = 18 - 5
10) x = 13
