Answer:
Width is 8 and the Length is 19.
Step-by-step explanation:
x = width
2x + 3 = length {length is 3 more than twice width}
Perimeter of a rectangle is 2(width) + 2(length)
2x + 2(2x + 3) = 54 {perimeter = 2(width) + 2(length)}
2x + 4x + 6 = 54 (used distributive property)
6x + 6 = 54 (combined like terms)
6x = 48 (subtracted 6 from both sides)
x = 8 (divided both sides by 6)
2x + 3 = 19 (substituted 8, in for x, into 2x + 3)
The width = 8 and length = 19
Best of luck,
