Question

The ratio between length and breadth of a rectangular plot is 5:3 respectively and its perimeter is 80 metres . What will be its area in sq. metres ?​

Answer 1

Step-by-step explanation:

Let the common multiple be x.

The ratio between length and breadth of a rectangular plot is 5x:3x

Length=5x ; Breadth=3x

Perimeter = 2(l+b)

80 = 2(5x + 3x)

80 = 2×8x

80 = 16x

80/16 = x

5 = x

Length=5x =5×5=25

Breadth=3x =3×5=15

Area = l×b

=25×15

=375.
