Question

A rectangle has a perimeter of 46 cm with a length of 12 cm. What is its width

Answer 1

11 cm

Explanation:

Given:

Perimeter = 46 cm

Length = 12 cm

To Find:

Width = ?

Solution:

Perimeter of Rectangle = 2( l + b)

We know the value of length

So, we can express this as a linear equation,

`2(l + b) = 46 \\ 2(12 + b) = 46 \\ 24 + 2b = 46 \\ 2b = 46 - 24 \\ 2b = 22 \\ b = (22)/(2) \\ b = 11`

So therfore, the width/breadth of the rectangle is 11.
