Answer:
x = 8.5
L = 17
W = 6.5
Step-by-step explanation:
P = 2*(L + W)
W = x - 2
L = 2x
P = 47
47 = 2 * (2x + x - 2)
47 = 2 * (3x - 2) Remove the brackets.
47 = 6x - 4 Add 4 to both sides.
47 + 4 = 6x - 4+4 Combine
51 = 6x Divide by 6
6x/6=51/6 Combine
x = 8 3/6 or 8.5
x = 8.5
========
L = 2*x
L = 2*8.5
L = 17
=====
W = x - 2
W = 8.5 - 2
W = 6.5
Answer:
x=8.5, length is 17, and width is 6.5
Step-by-step explanation:
To solve for x, you would add the two sides together, getting x-2+2x+3x-2. Now, you would multiply this figure by two, because you only have half of the perimeter as of now. (3x-2)*2+6x-4. Now, because the perimeter is 47, you have this equation
6x-4=47
Add four to both sides
6x=51
Divide by 6
x=51/6=8.5
Now, you would plug this into both of the other sides of the rectangle.
The length, or the longest side, measures 2x
2*8.5=17
The width, or the shorter side, measures x-2
8.5-2=6.5
Hope this helped
