Exercise 39 Page 600

Use the formula for area of a rectangle.

1.5ft^2

Practice makes perfect

To find the area of the square, we will use the formula for calculating the area of a rectangle. A=l * w We will substitute the given measurements, l=3 ft and w= 12 ft, into the formula to calculate A.

A=l * w

l= 3, w= 1/2

A= 3* 1/2

MoveLeftFacToNumOne

a* 1/b= a/b

A=3/2

Calculate quotient

A=1.5

The area of the square is 1.5ft^2.
