the perimeter of a rectangle is 24 in. and its length l is 3 times the width w. what is the length and width of the rectangle?
a.(3,9)
b.(14.4,4.8)
c.(12,4)
d.(9,3)

A)3,9

Step-by-step explanation:

lets take the length as "x"

since the width is 3 times the length we can use 3x to represent the width

formula for perimeter: 2(l)+2(w)

2(x)+2(3x)=24

2x+6x=24

8x=24

8x/8=24/8

x=3

if x is 3, the length is 3

if x is 3, the width, 3x is 9, (3*3)

yes
