Question

the breath of a rectangular field is 3/7 times of its length. find the dimensions of the rectangular field, if its perimeter is 40​

Answer 1

Answer:

Length of the rectangular field is 14, and it's breadth is 6.

Step-by-step explanation:

Let's assume that, the length of the rectangular field is x

According to the problem, it's breadth is $\frac{3x}{7}$

And, $2(x + \frac{3x}{7} ) = 40$

$=>x(1 + \frac{3}{7} ) = 20$

$=>x = \frac{7}{7 + 3} . (20) = (7).(2) = 14$

∴ $\frac{3x}{7}$ = $\frac{3}{7} . 14$ = 6

∴ Length of the rectangular field is 14, and it's breadth is 6.
