# GCF and area

How do you feel about mathematics now that you have completed MAT 115? Describe some coping mechanisms you developed in MAT 115 that you can use for your next math course.

Example: Find the GCF of 24 and 18

Example: Calculate the area of a circle that has a radius of 8 cm (use 3.14 for pi).

Example: Calculate the area of a parallelogram that has height of 4.7 meters and a base of 3.2 meters

Example: Consider the number 5.74391

(a) round the number to the nearest tenths place.

(b) round the number to the nearest hundredths place.

(c) round the number to the nearest ten-thousandths place

Example: Ms. Axia is going to build a rectangular fence in her backyard. The length of the rectangular fence is 16 feet and the width is 25 feet. Find the perimeter of the rectangular fence

I used to hate mathematics and didn't want to have anything to do with it. Now I find that mathematics could be interesting after I have completed MAT 115. Moreover, mathematics is much more concrete rather than abstract to me now.

One of the coping mechanisms is to find the context to apply what was being learned from the course. For example, I learned about the ...
