Im guessing the first answer
Answer:
Find the area of each triangle and then add it up. As you are aware, to find the area of a triangle the equation is B times Height divided by 2. And to make it easier do the top left triangle and the top right triangle, add them together and then divide that by 2.
Step-by-step explanation:
3 time 5 equals 15 divided by 2 equals 7.5
5 times 8 equals 40 divided by 2 equals 20
7.5 plus 20 equals 27.5
27.5 times 2 equals 55
therefor your answer should be 55m
10x20x2=$400
All you have to do is find the area of the floor(10x20=200),then you just multiple the area by the cost(200x$2=$400),and that is how you find the cost.
1 + 2 + 3 + 4 + 5 + 95 + 96 + 97 + 98 + 99. = 500
