You can first find the values of each of the function individually and add the two function up.
42 - 47
Polygons are
triangle, trapezoid, triangle, parallelogram, rectangle and parallelogram
The area of triangles = 1/2 * base * haight.
Area of the parallelograms = height * base.
Area of rectangle= width * length
Area of trapezoid = 1/2 * (a + b) * height where a and b are the opposite parallel sides
The perimeters = sum of the sides of the polygons.
The answer is C if not sorry
