Question

The area of a rectangle whose perimeter is 400m and the ratio in length and breadth is 3 ratio 1, is solutions

Answer 1

Answer:

Step-by-step explanation:

Let the ratio be 3x and x

Perimeter=2(l+b)

400=2(3x+x)

400=8x

400/8=x

50=x

Then,

3x=3×50=150

x=50

Area of rectangle=l×b

=150×50

=7500
