Question

He length of a rectangle is three times its width. The perimeter of the rectangle is at most 112 cm.

Answer 1

The equation relating length to width
L = 3W
The inequality stating the boundaries of the perimeter
LW <= 112
When you plug in what L equals in the first equation into the second equation, you get
3W * W <= 112
evaluate
3W^2 <= 112
3W <= $4 \sqrt{7}$
W <= $\frac{4 \sqrt{7} }{3}$ cm

Answer 2

Answer:

the answer is 2w+2*(3w)≤112

Step-by-step explanation:

If the rectangle is three times the width and the perimeter is 112 cm then we do 2w+2*(3w)≤112 since it is bigger or the same as 112

btw the other guy is so wrong
