Question

A rectangular field measures 40m by 25m. There is a rectangular flowerbed in the centre of the field, which is 5m away from each side of the rectangular field. Find the area which is not covered by the flowerbed.

Answer 1

Find the length and breadth of the flowerbed:

Length = 40 - 5 - 5 = 30 m

Breadth = 25 - 5 - 5 = 15 m

Find the area of the flowerbed:

Area = Length x Breadth

Area = 30 x 15 = 450 m²

Find the area of the rectangular field:

Area = length x breadth

Area = 40 x 25 = 1000 m²

Find the area not covered by the flowerbed:

Area = 1000 - 450 = 550 m²

Answer: The area is 550 m²

Answer 2

Finding the Area of the Rectangle field -

Length = 40 m

Breadth = 25 m

Area = 40 x 25 = 1000 m^2

______________________________

Finding the sides of the flower bed -

Given , each side 5 m .

Length = 40 - 10 = 30 m

Breadth = 25 - 10 = 15 m

_______________________________

Finding the Area of the flower bed -

Length = 30 m

Breadth = 15 m

Area = 30 x 15 = 450 m^2

_______________________________

Finding the Area that which is not covered by flower bed -

Area = 1000 - 450 = 550 m^2.

$\bold{Answer \: : \: Area \: is \: 550 \: m^2}$
