Question

the side of a rectangle is in the ratio 9:3 if its area is 1728 m square find its length and breadth​

Answer 1

Here the side of rectangle are in the ratio 9:3

Also, the area of the rectangle is given to be 1728 m².

We have to find length and breadth of the rectangle

Let the length and breadth of the rectangle be 9x and 3x

Then, area of rectangle = length × breadth

1728 = 9x × 3x

1728 = 27 x²

x² = 64

x = 8 m

So, length = 9x

= 9 × 8

= 72 m

breadth = 3x

= 3 × 8

= 24 m

Hence, the length and breadth of the rectangle will be 72 m and 24 m respectively.
