Question

Calculate the perimeter of this shape.
12 cm
18 cm

Answer 1

`12 +18 + x+y + z +w`

In this special case we know that
`x+y =12` and
`z+w =18` and for this case we can add all the values 12+18 +12+18=60 and that represent the perimeter

Explanation:

For this case we know that the perimeter is given by:

`12 +18 + x+y + z +w`

In this special case we know that
`x+y =12` and
`z+w =18` and for this case we can add all the values 12+18 +12+18=60 and that represent the perimeter
