Investigation 1 Question:

A. You are the manager of the bumper car arena and you want to find out the area and perimeter of this bumbercar arena

B.There is a fixed cost for these rail sections;

perimeter and the bumper floor tiles; area, what are the costs?? Answer:

There are 44 rail walls and

84 bumper floor tiles

It costs 2,100 dollars for the floor and

1,320 dollars to build the rail walls

I would get a piece of paper

and start counting the perimeter

and area and figure the question out Investigation 2 Question:

This is a odd irregular shape with no perfect sides

A.How do you find perimeters of odd shapes like this?

B.How do you find the area of odd shapes like this? Answer:

Using String for Perimeter and Using

grid paper to measure the area Investigation 3 and

Investigation 4 This is an example when there are

two rectangles with the exact area

but different peremeters. What was the Basic Big understanding/

idea of Investigation 3 and investigation 4? The big Understanding for investigation 3

is when a rectangle/Square or any other shapes

area is constant the perimeter is variable. The big understanding for investigation 4

si when a rectangle/ Square or any other shapes

perimeter is constant their area is variable. This is an example when there

are two rectangles with the same

perimeters but different areas. Investigation 5 Question:

How do you measure a parallelograms perimeter and area?

Before After Answer: This is how you find

the area easily Answer: You use the perpendicular height

to estimate the perimeter measure of the

parallelogram Investigation 6 Question:

How do you measure the area and perimeter of

a triangle easily? Answer:

By using this formula

Triangle x 2 = Parallelogram-

(Height / 2) X (Width / 2)=Perimeter of Triangle

Area / 2= Area of Triangle Investigation 7 Question:

how do you measure the area and the

circumference of a circle easily? Area Equation- R2 x pi = A Circumference Equation- D x pi = C Before After
