To compare ratios, write them as fractions. The ratios are equal if they are equal when written as fractions.
Two 2d shapes make a cylinder.
A square or rectangle for the tube in the middle.
And circles on the ends
Answer: 24 square units
Step-by-step explanation:
It appears the shaded area of the rectangle is half of the rectangle's area. This means if we find the area of the rectangle and divide it by 2 we will know the area of the shaded portion.
The formula for the area of a rectangle is 
Where
l is the length (8 for this)
w is the width (6 for this)
A is the area
However, since we are finding half the area we will divide lw by 2
Sub the values into the formula

T= -8 because -8-5 equals -13
