Answer:
Total Perimeter = 30 in
Total Area: 30 in²
Explanation:
First, do the perimeter of the triangle.
Equation: side+side+base = 3 + 4 + 5 = 12
Next is the perimeter of the rectangle.
Equation: 2(length + width) = 2·(5 + 4) = 18
Then, add the two perimeters:
12 + 18 = 30 in (Total Perimeter = 30 in)
Next, do the area of the triangle.
Equation: height • base/2 = 4 · 5/2 = 10
Finally, the area of the rectangle.
Equation: width • length = 4 · 5 = 20
Then, add the two areas:
10 + 20 = 30 (Total Area: 30 in²)
