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
a. multiply both sides with 11

if we multiply both sides by 11 it cancels out leaving us with the variable on one side of the equation making the answer b=66
I'm not really good at math but I would like to help.
