The perimeter is about 82 yards

first, the perimeter of the rectangles is 30*2 = 60 (the 7 is not a part of the overall perimeter so we do not need to add it)

the "perimeter" (circumference) of the 2 semi circles = (22/7)*7 = 22by using the formula C = pi*d (2 semi circles of the same diamter = 1 circle)

now just add the 2 answers
22 + 60

artcher [175]

Answer:

12(3y+2x)

Step-by-step explanation:

In this question, we are asked to give an expression that represents the total cost of shorts for the players.

He is ordering 2 pairs of short and 3 shirts. Hence, per player, he would be spending the following:

2 pairs of shorts at x dollars each. Cost here is just $2x

3 shirts at y per one. Cost is $3y

Per player he is spending a total of 3y + 2x

Now, there are people to cater for. The total amount to spend will now be 12(3y + 2z )
