Width
Length
Explanation:
Given:
Width
= x Length
= 2x - 5 Perimeter
= 50
"Perimeter" = 2xx "length" + 2 xx "width"
Substitute:
50 = 2(2x - 5) + 2(x)
Simplify:
50 = 4x - 10 + 2x
50 = 6x - 10
60 = 6x
x = 10
Substitute (FINALLY)
Width:
x = 10
So width
Length:
2x - 5 = 2(10) - 5
= 20 - 5 = 15
So length
