Question

Find the breadth of a rectangular room, If its length is 40m and its area is

1200m2 also find its perimeter.

Answer 1

Area = length x breadth
1200=40xbreadth
1200/40=breadth
Breadth=30
Perimeter = 2( length + breadth)
Perimeter= 2(40+30)
Perimeter= 140

Answer 2

Step-by-step explanation:

area=l×b

1200=40×x

1200/40=x

30=x

perimeter=2(l+b)

=2(40+30)=140 m
