The length of a table is 15 inches more than its width. If the area of the table is 700 square inches, what is its length?
Length is 35 inches
Let the width be x inch.
so, length will be (x+15) inches.
The table is rectangular in shape. So, its area will be = (Length * width) sq. unit.
Hence as per question, (x+15)*x = 700
or, (x-20) = 0, (x+35)= 0
or, x = 20, x = -35
width cannot be negative. so,
Hence x i.e. width = 20 inches and Length is (20+15) or 35 inches
