Question

1=12.6cm; w=14.8cm; p=

Answer 1

We are given the length and width of a rectangle and we need to find perimeter- the distance around the shape

$l$ = 12.6 cm

w = 14.8 cm

The formula for the perimeter of a rectangle is

Perimeter = 2$l$ + 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 $l$ 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
