Answer: Perimeter- 88m Area- 207sqm
Step-by-step explanation: To find the perimeter, you have to sort of split the shape into simple boxes. To find the line at the bottom, you have to add 18+11 because you can see that they match the line in the bottom. 18+11=29. You then have to find the P of the left. With the same method, you do 6+9, which equals 15. You add all of the sides together to get 88m. To find Area, you split the boxes into 2 smaller boxes. you then do 18x6 to get 108 for the top box. And 11x9 which equals 99. You add them together to get the area, 207! Hope that makes sense!!!
70.13047293 because if I convert all the fractions to decimals and and some parentheses we get this: ((2 + 489.05357142857) /1.167)/6 and that is equal to 70.13047293.
