Answer 2

Question -

The ratio of length to the breadth of a rectangle is 5: 3 if the perimeter of the rectangle is 144 m, what is the length of the rectangle?

Solution -

Let the length(l) of the rectangle be 5x and breadth (b) of the rectangle be 3x

Now,

We know that,

$Perimeter \: of \: rectangle = 2(l + b)$

By putting the values we will get -

$\implies144 = 2(5x + 3x)$

$\implies144 = 2 \times 8x$

$\implies 16x = 144$

$\implies x = \frac{144}{16}$

$\implies \: x = 9$

Length of the rectangle = 5×9=45m

Breadth of the rectangle = 3×9=27m

Therefore the length of the rectangle is 45m
