Question

the length and breath of a rectangle are in the ration 4 : 3 if it's perimeter is 154 cm find its length and breath ​

Answer 1

$The \: Length \: is \: 44 \: cm \: and \: Breadth \: is \: 33 cm.$

Step-by-step explanation:

Given :

Ratio = 4 : 3

Perimeter = 154 cm

To find :

Length and Breadth

Solution :

Let the -

Length = 4y

Breadth = 3y

$\boxed{\tt{Perimeter=2(Length+Breadth)}}$

$⟹ 154 = 2(4y + 3y)$

$\implies154 = 8y + 6y$

$\implies154 = 14y$

$\implies y = 154/14$

$\implies \: y = 11$

$★ Length -$

$\implies 4(11)$

$\implies 44 cm$

★ Breadth -

⟹ 3(11)

⟹ 33 cm

therefore The Length is 44 cm and Breadth is 33 cm.
