l=315w=75
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=315 and width w=75 into the formula for the perimeter of a rectangle.
2⋅315+2⋅75
Multiply 2 by 315.
630+2⋅75
Multiply 2 by 75.
630+150
630+150
Add 630 and 150.
780
Find the Perimeter rectangle (315)(75)
