Answer:
390 minutes
Step-by-step explanation:
162 / 3 = 54
351 / 54 = 6.5
6.5 x 60 = 390 minutes
The answer to m2=91 is 40.5
if 1 inch is added, you would add 2 inches to to each side of rectangle.
You would have: W+2, and, L+2,
Now let W+2 = x and, L+2 = y
Total area = x*y=M
If 1 inch is added again, like above you add 2 inches to both sides, you would then have:
(x+2)(y+2)=M+52;
xy+2x+2y+4=M+52;
xy=M
2x+2y=48
x+y=48/2=24
Now solve :
W+2+ L+2=24
W+L=20
The perimeter is 2(W+L)=20*2 = 40 inches.
![x^{ \frac{m}{n} } = \sqrt[n]{ x^{m} }](https://tex.z-dn.net/?f=%20x%5E%7B%20%5Cfrac%7Bm%7D%7Bn%7D%20%7D%20%3D%20%5Csqrt%5Bn%5D%7B%20x%5E%7Bm%7D%20%7D%20)
