Lesson Steps

Step	Type	Explanation	Answer
1	Problem	The perimeter of a rectangle is 24 meters. The width is 6 meters. What would the length be?
2	Step	The perimeter(p) of a rectangle is	24 mtrs.
3	Step	The width(w) of a rectangle is	6 mtrs.

Problem

The perimeter of a rectangle is 24 meters. The width is 6 meters. What would the length be?

Step

The perimeter(p) of a rectangle is

24 mtrs.

Step

The width(w) of a rectangle is

6 mtrs.

Hint

To find the length(l) of a rectangle

p = 2(l + w)

l = \$p / 2\$ - w

Step

Substitute the values by using length formula

l = \$24 / 2\$ - 6

Step

After division, we get

l = 12 - 6

Step

After subtraction, we get

Step

Then the length of a rectangle is 6 mtrs

SumUp
