Answer:
16 inches
Explanation:
A rectangle has two pairs of equal sides. The known width of this rectangle is 8 inches, so two of the four sides are 8 inches long, which add up to 16 inches. To find the length of the rectangle, find the remaining perimeter and divide it into two equal parts. 48 - 16 is 32, so the two lengths of the rectangle add up to equal 32. To find the length of one side length, divide 32 by 2. 32/2 is 16, so the length of the rectangle is 16 inches.
