Answer 1

Answer:

Each side of flower bed =3.8 m

Area =3.8×3.8sq.m

Area of flower bed before extension =14.44 sq m

If it is extended by digging a strip of 50 cm wide all around it, then the new side will be =3.8+1.0=4.8 m

Area of the flower bed after extension =4.8×4.8 

Area of enlarged flower bed =23.04 sq m

Increase in the area of flower bed =23.04−14.44=8.6 sq m
