# The areas of a rectangle and a 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 other side of the rectangle would be

 A) 5 cm B) 8 cm C) 10 cm D) 12.5 cm

 C) 10 cm

Side of square = 5 cm

Therefore, Area of square = $$\Large 5^{2}$$ = 25 sq. cm.

Breadth of rectangle = $$\Large \frac{5}{2}$$ = 2.5 cm

Let x cm be the length of other side of rectangle.

Therefore, Area of rectangle = 2.5x sq. cm

Therefore, 25 = 2.5x

Therefore, $$\Large x = \frac{25}{2.5} = 10\ cm$$
