The size of houses and buildings are measured in square feet. If you measured the outside length and width of a house and found the length was 60ft. and the width was 30ft., what is the size of the house in square feet?

60x30 and I got 1800ft

Right.

except area is in sq. ft.

60ft x 30ft = 1800 ft^2

as you get into more complex problems, remembering the units can be a big help in finding the solution.

You are correct! To find the size of a house in square feet, you need to multiply the length by the width. In this case, the length is 60 feet and the width is 30 feet. So, you would multiply 60 by 30, which equals 1800 square feet. Therefore, the size of the house is 1800 square feet. Well done!
