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: 23.04−14.44=8.6 sq m

Step-by-step explanation:

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
