A rectangle has a length of (x + 3) centimeters and a width of image x centimeters. If the perimeter is 24 centimeters, what is
the length of the rectangle? A. 9 cm B. 3 cm C. 14 cm D. 7 cm PLEASE HELP WILL MARK BRAINLIEST.
1 answer:
2(x + 3) + 2x = 24
2x + 6 + 2x = 24
4x = 24 - 6
4x = 18
x = 3.5
length is (x + 3), so Sub x = 3.5 into (x + 3)
3.5 + 3 = 6.5
