Answer 2

Answer:

The area of the remaining part of the Rectangular land is 43 m².

Step-by-step explanation:

Given :

Square flower beds = 4

Sides of the flower beds = 1m 50 cm

Dimensions of the rectangular land = 8m long and 6m 50 cm wide

To find :

Area of the remaining part of the land

Solution :

$\textsf{\underline{\underline{Area of the rectangular land : }}}$

Convert 6m 50 cm into m

⇒ 600 cm + 50 cm

⇒ 650 cm

650 cm into m

⇒ 650 ÷ 100 ........ [1m = 100cm]

⇒ 6.5 m

★ Area = Length × Breadth

⇒ 8 × 6.5

⇒ 52 m²

Area of the Rectangular land is 52 m².

$\rule{300}{1.5}$

$\textsf{\underline{\underline{Area of the square flower bed : }}}$

Convert 1 m 50 cm into m

⇒ 100 cm + 50 cm

⇒ 150 cm

150 cm into m

⇒ 150 ÷ 100 ........ [1m = 100cm]

⇒ 1.5 m

★ Area = Side × Side

⇒ 1.5 × 1.5

⇒ 2.25 m²

Area of the Square flower bed is 2.25 m².

$\rule{300}{1.5}$

$\textsf{\underline{\underline{Area covered by the flower beds : }}}$

As there are 4 flower beds, the area of one flower bed would be multiplied by 4.

⇒ 2.25 × 4

⇒ 9 m²

Area covered by the flower beds is 9 m².

$\rule{300}{1.5}$

$\textsf{\underline{\underline{Area of the remaining land :}}}$

Area of the remaining land = Area of Rectangular land - Area covered by the Square flower beds

⇒ 52 - 9

⇒ 43 m²

$\therefore$ The area of the remaining part of the Rectangular land is 43 m².
