The area of a rectangle and square are equal. The side of the square is 5 cm and the smaller side of the rectangle is half that of the square. The length of the other side of the rectangle would be

10 cm

According to the question:

Side of square = 5 cm, breadth of rectangle = 2.5, length = ?

As, area of square and rectangle is equal, we can say that:

(side)² = length x breadth

(5)² = length x 2.5

25 = length x 2.5

length = \(\frac{25 }{ 2.5}\)

length = 10
