A rectangular field is twice as long as it is broad. It has an area of 128. What will be the length of the field?

C) 16


As the length is twice that of the width, the rectangle can be divided into two squares each of area = 128/2 = 64. Each square has width =\(\sqrt{64}\)= 8 and length = \(2 \times \text { width }=16\)
