Question

15. The area of the floor of a room is 45 sq. m. If the length is 9 m, find its perimeter.​

Answer 1

Step-by-step explanation:

GIVEN

AREA OF FLOOR=45

LENGTH =9

AREA OF FLOOR=LENGTHXBREADTH

45=9XBREADTH

5=BREADTH

THEREFORE PERMITER OF FLOOR = 2(L+B)

=2(9+5)

=2(14)

=28

Answer 2

Answer:

28 m

Step-by-step explanation:

a = l*b

45= 9*b

b= 45/9

b= 5m

P= 2(l+b)

P= 2( 9+5 )

P= 2*14

P= 28 m
