Given :-

1. flower bed is 1 m 80 cm long .
2. it is enlarged by digging a strip 20 cm wide all around it find the area of the enlarged flower bed and also the increase in area of the flower bed

To find :-

find the area of the enlarged flower bed and also the increase in area of the flower bed

Solution :-

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

1 m = 100 cm

80 cm = 80

100

80 cm = 0.8 m

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

Area of square bed = Side? 3.24m²

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

1 m = 100 cm

20cm = 20

100

20 cm = 0.2 m

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

Area of enlarged flower bed = Side? 2.22 = 4.84m²

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.
