Note that a rectangle has 4 sides
It gives us the measure of the length and width
The formula for perimeter is P = 2l + 2w
(P meaning perimeter, l meaning length, w meaning width)
Multiply 6.5 and 2.5 by 2 and add the products together
(6.5 * 2) + (2.5 * 2)
13 + 5
9514 1404 393
80
If N is the total number of coins, then the number of quarters is ...
