This is a type of permutation problems in statistics. A permutation is a way in which the set of numbers can be arranged or order. In mathematics permutation relates to the act of ordering or arranging all the set of numbers into some sequence or order, or if the set is already in order or arranged its element the process is called permuting. Well, there are seven ways the first place can come in, then 6 ways for a second, and then 5 ways for third... so we multiply the 3 ways to get on how many different ways the first three finishers come in. 7*6*5 = 210 ways
these numbers can’t go into each other so therefore the answer is not possible

Answer:
the area of the house shaped thing is 60m and the area of the circle is 25.748
Step-by-step explanation:
to find the area of the house thing, you find the area of the triangle base×height divided by 2, which is 20. then you find the area of the rectangle 8×5= 40, add them together to get 60.
to get the area of the circle you do diamer×pi 8.2×3.14= 25.748
