Question

length 10m Area 120sq metre find the breadth and perimeter

Answer 1

Area=l*b
120=10*b
b=120/10
b=12m
so, perimeter =2(l+b)
=2(10+12)
=2*22
=44m

Answer 2

let the breadth be X
then it's area = 10m*X m=10x Meter square

according to the problem,

10x =120
X=120/10
X=12

breadth =12m ,length =10m
perimeter of the rectangle =2(length +breadth)meters
=2(10+12)
=2(22)
=44meters

therefore the breadth is 12m and the perimeter is 44m.



hope helps u dear... thnxx
