l=12w=14
The perimeter of a rectangle is equal to the sum of all sides of the rectangle.
length+length+width+width=2⋅(length)+2⋅(width)
Substitute the values of the length l=12 and width w=14 into the formula for the perimeter of a rectangle.
2⋅12+2⋅14
Multiply 2 by 12.
24+2⋅14
Multiply 2 by 14.
24+28
24+28
Add 24 and 28.
52
Find the Perimeter rectangle (12)(14)
