Question

Susan makes a rectangular rug that has an area of 300 square inches and a width of 15 inches. What is the length of the rug?

Answer 1

The width is 15, making the length having to be multiplied by 15 to be 300, which is 15 times 20 =300

Answer 2

Area = Base x Height
To undo this, divide the area by the side that you know, in this case
300/15=20
