Question

9. Five square flower beds each of sides 1 m are dug on a piece of land 5 m long and 4
m wide. What is the area of the remaining part of the land?



​

Answer 1

$\: \huge\bf\underline \red{\underline{Answer}}$

$Side \: of \: square \: bed = 1 m$

$Area \: of \: square \: bed = side \times side$

$= > 1 m \times 1 m = 1 {m}^{2}$

$∴ Area \: of \: 5 \: square \: beds = 1 \times 5 = 5 {m}^{2}$

Now,

$Length \: of \: land = 5 m$

and

$breadth \: of \: land = 4 m$

$∴ Area \: of \: land = length \times breadth$

$= > 5 m \times 4 m = 20  {m}^{2}$

$Area \: of \: remaining \: part = Area \: of \: land – Area \: of \: 5 \: flower \: beds$

$= > 20 {m}^{2} – 5 {m}^{2} = 15 {m}^{2}$

Answer 2

Question :

Five square flower beds each of sides 1 m are dug on a piece of land 5 m long and 4m wide. What is the area of the remaining part of the land?

Solution :

Step-by-step explanation :

Given :

Side of square bed = 1m

Length of land = 5m

Breadth of land = 4m

To Find :

Area of remaining part of the land = ?

Solution :

Area of 1 square bed = (Side)²

= (1)²

= 1 × 1 = 1m²

Area of 5 square beds = 1m² × 5

= 5m²

Now,

Area of land = Length × Breadth

= 5 × 4

= 20m²

So ;

Area of remaining part of land =

Area of Land - Area of square beds

= 20m² - 5m²

= 15m²
