Four flower beds having sides 2 m long and 1 m wide are dug at the four corners of a garden that is 15 m long and 12 m wide. How much area is now available for laying down a lawn?

Correct Answer

Step 1: Area of the garden = length × width = 15×1215 \times 12 = 180 sq m

Step 2: Area of one flower bed = 2×12 \times 1 = 2 sq m

Step 3: Area of four flower beds = 4×24 \times 2 = 8 sq m

Step 4: Area available for lawn = 180 - 8 = 172 sq m

Answer: The area available for laying down a lawn is 172 sq m.
