Question

11. Four square flower beds each of side 1 m are dug on a piece of land 7 m long and 3 m
wide. What is the area of the remaining part of the land​

Answer 1

Answer:

Area of the remaining part of the land is 17m²

Explanation:

Side of 1 square flower bed = 1m

Area of a square = ( side )²

Area of 1 flower bed = ( 1m )²

Area of 1 flower bed = 1m²

Area of 4 flower bed = 1m² × 4

Area of 4 flower bed = 4m²

length of the land = 7m

Width of the land = 3m

The land is in the shape of a rectangle so we could use the formula for area of a rectangle.

Area of a rectangle = length × width

Area of the land = 7m × 3m

Area of the land = 21m²

Area of remaining part of the land = Area of the land - Area of four flower beds

Area of the remaining part = 21m² - 4m²

Area of the remaining part = 17m²

17m² is the answer.

Answer 2

Question :-

• Four square flower beds each of side 1 m are dug on a piece of land 7 m long and 3 m wide. What is the area of the remaining part of the land ?

Given :-

• Area of 1 flower bed = 1 m
• Area of 4 flower bed = 4m
• Length of piece of land = 7m
• Breadth of piece of land = 3m

To Find :-

• What is the area of the remaining part of the land ?

Solution :-

$\qquad \quad {:} \longrightarrow \sf \boxed{\bf{Area \: of \: piece \: of \: land \: = \: Length \: \times \: Breadth }}$

$\qquad \quad {:} \longrightarrow \sf {\sf{Area \: of \: piece \: of \: land \: = \: 7\: \times \: 3}}$

$\qquad \quad {:} \longrightarrow \tt {\tt{Area \: of \: piece \: of \: land \: = \: 21 {m}^{2} }}$

━━━━━━━━━━━━━━━━━━━━━━━━━

Area of Remaining part = Area of Land - Area of Flowers beds.

$\qquad \quad {:} \longrightarrow \sf {\sf{Area \: of \: remaining \: of \: land \: = \: 21\: - \: 4}}$

$\qquad \quad {:} \longrightarrow \sf {\sf{Area \: of \: remaining \: of \: land \: = \: 21\: - \: 4}}$

$\qquad \quad {:} \longrightarrow \sf {\bf{Area \: of \: remaining \: of \: land \: = \: 17{m}^{2}}}$

━━━━━━━━━━━━━━━━━━━━━━━━━

So, The area of remaining part = 17m²
