Question

the length and breadth of a rectangular plot are in the ratio 3 is to 5 if the perimeter is 28 M find its area​

Answer 1

let the measure be x

ratio =3x:5x

perimeter of rectangle =2(l+b)

28m. =2(3x+5x)

28m. =2 * 8x

28m/2=8x

14m. = 8x

14m/8=x

1.75. =x

length=3 * 1.75=5.25m

breadth=5*1.75=8.75

area =l * b

=5.25 * 8.75

=45.9375
