Question

pel sy .
side of a square flower bed is 1 m 80 cm. It is enlarged by digging a strip 20 cm wide all around it.
he area of the enlarged flower bed​

Answer 1

Increase in the area of the flower bed = 4.84-3.24 = 1.6 sq. m.

Hence the area of the enlarged flower bed =is 4.84 sq.

Answer 2

Answer:

The area of the enlarged flower bed =is 4.84 sq.m. and increase in the area is 1.6 sq.m

Step-by-step explanation:

The side of a square flower bed is 1m 80cm long

1 m = 100 cm

80 cm = \frac{80}{100}

100

80

80 cm = 0.8 m

So, the side of a square flower bed is 1.8 m

Area of square bed = Side^2 = 1.8^2 = 3.24 m^2Side

2

=1.8

2

=3.24m

2

Now we are given that it is enlarged by digging a strip 20cm wide all around it

1 m = 100 cm

20 cm = \frac{20}{100}

100

20

20 cm = 0.2 m

So, new side = 1.8+0.2+0.2 =2.2 m

Area of enlarged flower bed = Side^2 = 2.2^2 = 4.84 m^2Side

2

=2.2

2

=4.84m

2

Increase in the area of the flower bed = 4.84-3.24 = 1.6 sq.m.

Hence the area of the enlarged flower bed =is 4.84 sq.m. and increase in the area is 1.6 sq.m.
