The central hall of a school is 22 meter long and 15.5 meter wide. A carpet is to be laid on the floor leaving a strip of 75 cm. find the area of the carpet and the area of the strip left uncovered​

Answer 1

Answer:

area of rectangular hall = l × b

22 × 15.5 = 341 sq m (1)

area of carpet

length = 22 - 1.5 = 20.5

width = 15.5 - 1.5 = 14

l × b

20.5 × 14 = 287 sq m (2)

area of strip uncovered

(1) - (2)

341 - 287 = 54 sq m
