We are given the length and width of a rectangle and we need to find perimeter- the distance around the shape
[tex]l[/tex] = 12.6 cm
w = 14.8 cm
The formula for the perimeter of a rectangle is
Perimeter = 2[tex]l[/tex] + 2w
This makes sense because around the shape there are 2 equal lengths and 2 equal widths- one of the definitions of a rectangle
To find perimeter plug in the know vales of [tex]l[/tex] and w
Perimeter = 2(12.6 cm) + 2(14.8 cm)
Now use PEMDAS to solve
= 25.2 cm + 29.6 cm
= 54.8 cm
The perimeter of the rectangle is 54.8 cm
