Sorry, I can't draw a picture, but I can help answer the question...

The way to determine the area of a square or rectangle is to multiply the base and the height, which in this case, is 24 and 18. So 24 times 18 is 432. Therefore, the amount of glass needed to repair the window is 432 inches squared.

Hope that helps!

Claire walked her dog 2 1/5 miles. Carson walked her dog 1 3/4 times as far as Claire did. How many more miles did Carson walk h
Anon25 [30]

The word "times" means you have to multiply.

2 1/5 times 1 3/4 is 3 17/20.

The phrase "how many more" means you have to subtract.

3 17/20 minus 2 1/5 is 1 13/20.

Carson walked her dog 1 13/20 more miles than Claire did.

Sorry for the lazy explanations Imao
