How could I solve this problem?:

A lot measures 60ft by 100ft. The house on the lot measures 30ft by 50ft. What is the area if the lawn?

This is about reasoning strategy: Use multiple strategies

Draw a picture. Make a big rectangle that has dimensions 60x100. Inside that rectangle, make a smaller rectangle with dimensions 30x50. Based on the picture, what do you think you should do to solve for the lawn?

oh ok :) So then, would I multiply 60x100=6000

and 30x50=1500
then subtract 6000-1500?

Yes, you're right! :-)

thank you =]

To solve this problem, you can use the strategy of finding the area of the entire lot and subtracting the area of the house within it.

First, find the area of the lot by multiplying its length by width: 60ft x 100ft = 6000 square feet.

Next, find the area of the house by multiplying its length by width: 30ft x 50ft = 1500 square feet.

To find the area of the lawn, subtract the area of the house from the area of the lot: 6000 square feet - 1500 square feet = 4500 square feet.

Therefore, the area of the lawn is 4500 square feet.
