Write down two expressions for the perimeter of this shape, one with
brackets and one without
[ + 7
P (with brackets)
P (without brackets) =

Perimeter with brackets is:

perimeter without brackets is:

Step-by-step explanation:

We need to write two expressions for the perimeter of given shape, one with brackets and one without.

Length of side of shape = t+7

The formula used to find perimeter is:

Since the shape has 4 sides, we get:

So, perimeter with brackets is:

Now, finding perimeter without brackets:

So, perimeter without brackets is:
