Hello,
With what we know, let's set up an equation. The equation to find the perimeter of a rectangle is: P = 2( L + W)
We know the perimeter is = 7.2 meters
And we know the width is = 1.3 meters
Let's plug that into the equation.
7.2 = 2(1.3 + L)
Let's then distribute the 2 to what's in the parenthesis.
7.2 = 2.6 + 2L
If we then want to find the length, we need to subtract 2.6 from that side and also subtract it to the other side so that 2L is only left. After you do that, the equation simplifies to:
7.2 - 2.6 = 2L
The next step is to subtract 7.2 to 2.6, which is:
4.6 = 2L
Lastly, we want to get L by itself so we will divide l by 2, to cancel the 2 out, and then we need to also divide the left side with 2 also. And that will get you with:
4.6/2 = L
After you divide, L = 2.3 meters
Hope this helps! Have a great day =).

Answer:
So, after 6 months, they both have the same number of coins.
Step-by-step explanation:
Jack has 56 coins
Jill has 80 coins
Jack collect 12 coins per month
Jill collect 8 coins per month
Let after m months, they both have the same coin.
56 + 12 m = 80 + 8 m
12 m - 8 m = 80 - 56
4 m = 24
m = 6
So, after 6 months, they both have the same number of coins.
