Question

the perimeter of a rectangle is 200 m while thw differnce between height and breadth is 50m find area

Answer 1

let the breadth be x m
therefore length=x+50 m
now,perimeter=2(l+b)
200=2(x+50+x)
200/2=2x+50
100-50=2x
50/2=x
25=x
breadth=25m
length=25+50m=75m
now,area=l*b
               =75*25
              =1875
