Answer:
πr + (2l + b)
Step-by-step explanation:
The figure is a composite figure, consisting of a semicircle and a rectangle :
The perimeter of a rectangle is the sum of the sides ;
Perimeter of semicircle is the 2πr/2 (Circumference / 2)
For the triangle, we take the sum of 3 sides ;
Length + length + breadth = 2l + b
Hence, the perimeter is :
2πr/2 + 2l + b
πr + (2l + b)

375 hamburgers were sold on Wednesday
<em><u>Solution:</u></em>
Let "h" be the number of hamburgers sold
Let "c" be the number of cheeseburgers sold
To find: number of hamburgers sold on Wednesday
Given that local hamburger shop sold a combined of 686 hamburgers and cheeseburgers on Wednesday
Therefore,
number of hamburgers sold + number of cheeseburgers sold = 686
h + c = 686 ------- eqn 1
There were 64 fewer cheeseburgers sold than hamburgers
Number of cheeseburgers sold = number of hamburgers sold - 64
c = h - 64 ------- eqn 2
Let us solve eqn 1 and eqn 2
Substitute eqn 2 in eqn 1
h + h - 64 = 686
2h - 64 = 686
2h = 686 + 64
2h = 750
h = 375
Thus 375 hamburgers were sold on Wednesday
