Exercise 51 Page 549

Use the formula for area of a rectangle.

F

Practice makes perfect

To find the area, we will use the formula for calculating the area of a rectangle. A=l * w We will substitute the given measurements, l=5.8 and w=3.2, into the formula to calculate A.

A=l * w

l= 5.8, w= 3.2

A= 5.8 * 3.2

Multiply

A=18.56

While the area of the rectangle is 18.56cm^2, we need to round the result to the nearest tenth in order to fit the answer choices. Once we round our answer to 18.6cm^2, the correct option is F.
