Find the perimeter of this figure

128.52

Step-by-step explanation:

Find the area of the figure by splitting it into two shapes - a trapezoid and a semi-circle.

The area of a semi-circle is found using A = 1/2πr² where r = 6 since the diameter is 12. A = 1/2π(6)² = 56.52.

The area of the trapezoid is found using A = 1/2(a+b)h = 1/2(12 + 6)(8) = 72.

Together the area is 56.52 + 72 = 128.52.

x + 107

step-by-step explanation:

let's say that the number he had before the mistake was x. then, he will have 107 dollars more than this, so the answer is x + 107.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
