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

Answer:

B. 34m

Step-by-step 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

$P=24+10=34$

Answer 2

Answer:

The correct answer is option B. 34 m

Step-by-step 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
