Question

Each side of a square flower bed is 3 m 80 cm long. It is extended by digging a strip
to
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:

Step-by-step explanation:

Each side of flower bed = 3.8 m

Area = 3.8 × 3.8

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
