How to find area of polygon

With any rectangle, when the dimensions are halved, the area of the resulting rectangle will always be. Another way to solve this is by calculating the area of the first rectangle. In this case we let. For the second rectangle our width becomes. Therefore rectangle one has an area 4 times larger than that of rectangle two.Calculate the area of each smaller shape, then add them all together to get the area of the whole shape. (This is what they did up above when they had us count squares to figure out the area of the big shape.) Each square is 1x1, so the area of each square is one. (First step: calculating the area of the smaller shapes.)The area of the shaded region is the difference between the area of the entire polygon and the area of the unshaded part inside the polygon. The area of the shaded part can occur in two ways in polygons. The shaded region can be located at the center of a polygon or the sides of the polygon. How to Find the Area of the Shaded Region? Perimeter is the distance around the outside of a shape. For example, if you walk around the edge of a playground, you're measuring its perimeter. Area is the amount of space inside a shape. For example, if you want to put new tiles on your kitchen floor, you need to know the area of the room to know how many tiles to buy.
