Question

A land is 5 m long and 2.5 m wide. Five square flower beds of 1 m length have been made in it. Find the area of remaining land.​

Answer 1

Answer:

30 km breadth 47km length

Answer 2

Given:

length of land: 5 m

breadth of land = 2.5 m

length of flower bed = 1 m

To find:

area of remaining land =?

Step-by-step explanation:

• Given land is 5 m long and 2.5 m wide.
• That means land is in a rectangular shape.
• The area of rectangular land is calculated by:

      ∴  area of land = length × breadth

                               = 5 × 2.5

                               = 12.5 m²

• Five square flower beds of 1 m length have been made on the rectangular land. Thus the area of square flower beds is calculated by

       ∴ area of square flower bed = 5 ×  length²

                                                       = 5 × 1 × 1

                                                       = 5 m²

• Hence the remaining area of land is calculated by subtracting the area of the square flower bed from the total area of land.

        ∴ area of remaining land = area of land - area of a square flower bed

                                                  = 12.5 - 5

                                                  = 7.5 m²

• Hence, the area of the remaining land is 7.5 m².
