1) the area of a rectangular lawn is 255m.sq .if it 's length is 15m,find its perimeter. 2) the area of a rectangular lawn is the same as the area of an

18mlong square. If the length of the rectangular lawn is 27m, find its perimeter

1) area of a rectangle=l*b=255msq. 15*b=255 b=255/15 =17m therefore the breadth of the lawn is 17m perimeter= 2(l+b) =2(15+17)=2*32=64m 2)area of the square===324m sq. area of the rectangular lawn = area of the square l*b=324 27*b=324 b=324/27=12m perimeter=2(l+b) =2(27+12)=2*39=78m
