l=5w=3
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=5 and width w=3 into the formula for the perimeter of a rectangle.
2⋅5+2⋅3
Multiply 2 by 5.
10+2⋅3
Multiply 2 by 3.
10+6
10+6
Add 10 and 6.
16
