Question

The breath and perimiter of a rectangle are 8cm and 64cm. find the length of the rectangle​

Answer 1

Given:

• Breadth = 8 cm
• Perimeter = 64 cm

To Find:

• Length of the Rectangle?

Formula Used:

$\\ \bigstar{\underline{\boxed{\tt\large{ \orange{Perimeter_{(Rectangle)} } = 2(l + b) }}}}$

Where

• l = length
• b = breadth

Solution:

Perimeter is given so we have to find the length of Rectangular Figure;

After substituting values,

$\implies$ p = 2(l + b)

$\implies$ 64 = 2(l + 8)

$\implies$ 64 = 2l + 16

$\implies$ 64 - 16 = 2l

$\implies$ 48 = 2l

$\implies$ 48/2 = l

$\implies$ l = 24 cm

Hence,

• The Length of the Rectangle is 24 cm.
