Answer:
The width is 7 inches and the length is 9 inches
Step-by-step explanation:
So we can divide 32 by 2 because we know perimeter is 2(l*w)
So it becomes 16, and it is now (l*w)
We know that the length is 2 inches longer so we subtract 2 from 16.
It then becomes 14 inches so therefore we can then divide it by 2.
14 divided by 2 is 7 and therefore we add 2 because we subtracted the two from earlier temporarily.
Therefore the width is 7 and the length is 9.

Step-by-step explanation:
Answer:
dogs = 2
cats = 80
Step-by-step explanation:
Here I will assume that cats and dogs are proportional
c = y d, if you substitue, you get
10 = y 4, which rearranged, becomes
y = 10/4 = 2.5
now that we know y, we can work out x and y, the missing dogs and cats
4 = 2.5 d
here, dogs = 2
c = 2.5 * 32
2.5 * 32 = 80
here, cats = 80
