The length of a rectangle is twice its breadth and its area is 288 cm2. Find the dimensions of the rectangle.
Let the length and breadth of a rectangle be 2x and x respectively
According to the question;
Area = 288 cm2
Area = length.breadth
x(2x) = 288 cm2
2x2 = 288
x2 = 144
x = 12 or x = – 12
x = 12 ( x cannot be negative)
length = 2.12 = 24 cm, breadth = 12 cm
