∙ 12y agoI don't know how to explain it but you count the boxes colored in then that's how many are on the other sides. I'm sorry if I gave you the wrong answer I'm only 9!
Area of rectangle with part of the shape missing = area of rectangle (lengthxwidth)-area of missing part.
Form an equation and solve it
You don't
The answer depends on what the shape is and what information is available.
look at the top part of the shape you're trying to find the missing length of then look at the bottom part then compare then subtract same for all sides
in order to find the perimeter of a shape add up all the sides measurements
Simple, Add all the sides of the shape up.
I do not no how about you find out what a polygon is then count the sides -A
Add All The Sides Up
count the sides or edges.
The formula to find the sum of the angles of any shape is: (sideCount-2)*180 If the shape has 11 sides the total interior angle is: 1620.
The answer will depend on what the shape is!
Answer depends on what the shape is and what other information is available.
Add the sides and the corners up.
Perimeter = The sum of the lengths of all sides of a shape
A shape does not have a sum. You can sum its angles, the lengths of its sides, the areas of its faces and so on. But the shape does not have a sum, in itself.
