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

B. 34m

Step-by-step explanation:

The perimeter of a rectangle is given by

where

Substitute the values into the formula to get

Simplify

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

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
