Question

Which of these can be the possible arrangements of a rectangular patio whose area is 31 sq feet.

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Area of a rectangle = length × width


The above rectangle has length 31 feet and width 2 feet. Its area = $31\times 2$
= 62 sq feet.


The above rectangle has length 15 feet and width 2 feet. Its area = $15\times 2$
= 30 sq feet.


The above rectangle has length 11 feet and width 3 feet. Its area is 33 sq feet.


The above rectangle has length 31 feet and width 1 foot.
Its area is $31\times 1$ = 31 sq feet.
This is the required arrangement of a rectangular patio whose area is 31 sq feet.
