Question

a rectangle has a length of 9 inches and an area of 48 inches. it’s width, w, is unknown. explain why the following equation cannot be solved to find the correct width of the rectangle? w+9=48

Answer 1

This equation cannot be solved to find the correct width of the rectangle because the formula for the area of a rectangle is area = base times the height. Therefore, you can't just simply subtract 9 from 48 to get the width. Instead, you have to divide 48 by 9 to find the width, since 48 is the area and 9 is the length.

hope this helps :)
