Question

Each side of a square flower bed is 3 m 80 cm long. It is extended by digging a strip
50 cm wide all around it. Find the area of the enlarged flower bed and also the increase
in the area of the flower bed.
​

Answer 1

Answer:

4.8m

Step-by-step explanation:

Square flower bed side =3.8m

area of flower bed =308*3.8=14.44msquare

it is increased by 0.5m

so its side =3.8+0.5+0.5=4.8m

so area of flower bed after increasing 0.5m=4.8*4.8=23.04msquare

so the increase area =23.04-14.44=8.6m
