Question

each side of a square flower bed is 2 metre 80 cm long it is extended by digging a strip 30 cm wide all around it find the area of the enlargest flower beds and also the increasing in the area of the flower bed

Answer 1

EFGH is the inner square whose side is 2m80cm and ABCD is the outer enlarged square we have to find out its area and between EFGH and ABCD 30cm wide stripe all around it.

Area of EFGH : Side × Side
: 2.80m × 2.80m
: 7.84 squre m

Length of AC : 2.80m + 0.30m + 0.30m
: 3.40m

Area of ABCD : 3.40m × 3.40m
: 11.56square m

The area of enlargest flower bed is: 11.56squre m

Area of the path : 11.56squre m - 7.84squre m
: 3.40squre m

3.40squre m is the increase in the area of flower bed.

Answer 2

Answer:

EFGH is the inner square whose side is 2m80cm and ABCD is the outer enlarged square we have to find out its area and between EFGH and ABCD 30cm wide stripe all around it.

Area of EFGH : Side × Side

: 2.80m × 2.80m

: 7.84 squre m

Length of AC : 2.80m + 0.30m + 0.30m

: 3.40m

Area of ABCD : 3.40m × 3.40m

: 11.56square m

The area of enlargest flower bed is: 11.56squre m

Area of the path : 11.56squre m - 7.84squre m

: 3.72squre m

3.72squre m is the increase in the area of flower bed.
