Find the perimeter of the shape on this centimetre grid.

the perimeter is 16

Step-by-step explanation:

The computation of the shape on this centimeter grid is shown below:

As we can see in the attached figure that the some portion is highlighted

So if we count that

like

So after counting it comes 16

Therefore the perimeter is 16

778-550=228

Jupiter's average is 778km away from the sun and Mars is 550 less kilometers away from the sun than Jupiter. So you just subtract 778 to 550 which equals to 228. Therefore the average distance Mars is 228km away from the Sun.

778 = d + 550

778 - 550 = d

228 = d
