Question

area of rectangle=84m^2, difference between length and breadth is 5m, Perimeter =?

Answer 1

let the breadth be x.
length=5+x
according to the question,
lenght *breadth=area
after solving we get
breadth =7cm.
length=12 cm.
perimeter=length+breadth
               =12cm+5cm
               =17cm.
