Question

Mrs. Sampson drew two polygons on the whiteboard as shown below.polygon A. 16.6cm 16.3 cm 15.25 cm 15.25cm 22cmpolygon B. 30 1/2 cm 28.75 cm 28.75 cm 30 1/2 cmHow much larger is the perimeter of Polygon B than Polygon A?

Answer 1

First we need to know that a perimeter is the sum of each side of a polygon.

Now Let's calculate each perimeter:

And for Polygon 2:

As we can see polygon B is larger than polygon A. To know how much it is lager we just need to subtract:

87.5 - 62.1 = 25.4

So the perimeter of polygon B is 25.4cm larger than polygon A.
