Answer:
the length is 41 inches, the width is 9 inches
Step-by-step explanation:
let "x" represent the width
if "x" represents the width, then "4x+5" represents the length
perimeter of a rectangle = 2(length+width)
100 = 2(4x+5+x)
100 = 2(5x+5)
100= 10x +5
10x = 100 - 5
10x = 90
x = 9
width is 9 inches, but you still need to solve for length
length = 4x+5"
4(9)+5=41
CHECK:
2(length+width) = 100
2(41+9) = 100
100=100
