Perimeter is 2 x length + 2 x width
We can write that as...
P=2L+2W
We also know the length and perimeter so we substitute and solve like this
90=2 x 27 + 2W
90=54+2W
90-54=54-54+2W (property of subtraction equality)
36=2W
Divide by 2 (property of division equality)
W=18
Thus, the width of the rectangle is 18 cm
9.8 The reasoning for this is simple. We have 235.2 ounces. We also have 24 boxes of crayons. We are going to put it in this order: ounces divided by the box of crayons. That is 235.2/24 =9.8. So, therefore there are 9.8 ounces of crayons in each box.
