l=9.1w=8.2

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=9.1 and width w=8.2 into the formula for the perimeter of a rectangle.

2⋅9.1+2⋅8.2

Multiply 2 by 9.1.

18.2+2⋅8.2

Multiply 2 by 8.2.

18.2+16.4

18.2+16.4

Add 18.2 and 16.4.

34.6

Find the Perimeter rectangle (9.1)(8.2)
