Question

Select the best answer for the question. 17. What's the perimeter of a rectangle with length 12 m and width 5 m? A. 17 m B. 34 m C. 60 m D. 49 m

Answer 1

The correct answer is option B. 34 m

Explanation:

Formula:-

Perimeter of rectangle

Perimeter = 2(l + b)

l - Length of rectangle

b - Breadth of rectangle

It is given that,length 12 m and width 5 m

To find the perimeter of rectangle

l = 12 m and b = 5 m

Perimeter = 2(l + b) = 2(12 + 5) = 2 * 17 = 34 m

Therefore the perimeter of rectangle = 34 m

The correct answer is option B. 34 m

Answer 2

B. 34m

Explanation:

The perimeter of a rectangle is given by

`P=2l+2w`

where
`l=12m,w=5m`

Substitute the values into the formula to get

`P=2(12)+2(5)`

Simplify

`P=24+10=34`
