Answer:
Width = 4 m
Length = 7 m
Step-by-step explanation:
given:
perimeter of a rectangle = 22m
L = 3 + W
perimeter = 2L + 2W
perimeter = 2 (3 + W) + 2W
22 = 6 + 2W + 2W
22 - 6 = 4W
W = 16 / 4
W = 4 m
L = 3 + W
L = 3 + 4
L = 7 m
check:
perimeter = 2L + 2W
22 = 2(7) + 2(4)
22 = 14 + 8
22 = 22 ---- OK
0,4 would be your new coordinates.
The second choice is the correct choice because a set of parallel lines has to have the same slope. Since the first equation given has a slope of 3/4, and the only answer choice with a slope of 3/4 is the second choice, the second choice is the correct answer. I hope that this helps :)
