What is the rise and run?
We use words RUN and RISE to describe the two legs of the right triangle. The RUN is the length of the horizontal leg, and the RISE is the length of the vertical leg. We assign a positive sign to the rise if it goes down to meet the graphed line.
What is perimeter and area called in mathematics?
The perimeter is the addition of the all the sides of the shape. For example if a rectangle has two sides which are 4cm and two sides which are 7cm, then the perimeter will be 4cm+4cm+7cm+7cm. The perimeter would therefore be 22cm. The area of a shape is gotten by multiplying the length and breadth of the shape. For example, in a rectangle witrh the same measurements above, the area will be 4cm x 7cm and that would 28cm. You have to use the square sign but I can't do that here.
