Answer 2

Correct Question:-

→ The measure of two adjacent sides of rectangle is in the ratio 11:10. If perimeter of rectangle is 84 cm. Then, find length and breadth of the given rectangle.

$\huge\underline\green{\tt Solution :}$

Let the common factor be ' x '  

So, length = 11x and breadth = 10x

∵ Perimeter of Rectangle = 2 ( l + b )

Now,

According to question

2 ( 11x + 10x ) = 84

⇒ 2 ( 21x ) = 84

⇒21x = $\dfrac{84}{2}$

⇒ 21x = 42

∴ x = 2

Therefore,

Length of the rectangle is 11 × 2 = 22 cm

Breadth of the rectangle is 10 × 2 = 20 cm

$\sf\blue{Verification :}$

2 ( 22 + 20 ) = 84

⇒2 ( 42 ) = 84

⇒84 = 84

L.H.S = R.H.S
