Question

The length of a garden is 50 meters and its width is 30 meters. If the biggest possible square land from the garden is removed, what area of the garden will still be left?

• A. 100 sq m
• B. 300 sq m
• C. 900 sq m
• D. 600 sq m

Answer 1

The correct option is D 600 sq m


Length of the garden = 50 m
Width of the garden = 30 m
Area of the garden = 50 $\times$ 30 = 1500 sq m

If the biggest possible square land of the garden is to be removed, then the side length of the square land should be maximum as well.
Since the garden is a rectangle, the largest square land that can be removed from it is of the length equal to the width of the rectangle.

Side length of the square land = 30 m
Area of the square land = 30 $\times$ 30 = 900 sq m
Area of the garden left = 1500 – 900 = 600 sq m
