Answer:
I think it's 12×54 but im probs wrong
Part A: One solution because the lines intersect one time.
Part B: (3,4) or x=3 and y=4 (depending on how you have to write it)
let w = width and 3w = length
perimeter is the distance around the outside of the object or P = 2L + 2W
2(3w) + 2w = 24
6w + 2w= 24
8w = 24
w= 3
3w= 9
Width is 3in. and length is 9in.
