Lisa has to cut her grandma's grass this weekend and wants to know exactly how much area she will be cutting. Calculate the area of the polygon. Be sure to show all your work and explain your answer.

398

Step-by-step explanation: First I find the area of the biggest triangle 20x20x1/2=200.

Then I find the area of the rectangle by cutting off the triangle at the end 6x30=180.

After that I find the area of the small triangle 6x6x1/2=18.

Finally, I add all the area up and 18+180+200= 398

Hope this helps :)

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

3+x
