Question

Which of the two room is bigger one those length and breadth of the floor are 10 and 8.5 metre or one those length and breadth of the floor are 9.5 metre and 9 metre​

Answer 1

Step-by-step explanation:

area of first room=8.5×ten =95square metre

area of second room= 9.5×9=85.5 square metre

henceforth second room is bigger than the first room..

Answer 2

$area\: of \: rectangle \: = l \: \times \: b$

1st

area of rectangle = 10 × 8.5 = 85m . sq

Therefore, The area of 1st room is 85m.sq

2nd

area of rectangle = 9.5 × 9 = 85.5m. sq

85m. sq < 85.5m. sq

Therefore, 2nd room encloses or covers more area.

To find which is bigger we first we have to find only area as we want to find enclosement.
