240 units²
Further explanation
Given:
- A rectangle with length = 20 units and width = 10 units.
- Isosceles triangle with base = 20 units and height = 4 units.
Question:
Find the total area of the shape shown below.
The Process:
Step-1: find out the area of rectangular
The area = length x width
The area = 20 x 10
Hence, the area of rectangle is 200 units².
Step-2: find out the area of isosceles triangle
The area = [tex]\frac{1}{2} \times base \times height[/tex]
The area = [tex]\frac{1}{2} \times 20 \times 4[/tex]
The area = 10 x 4
Hence, the area of triangle is 40 units².
Step-3: find out the total area
Let us calculate the sum of the area of rectangles and triangles.
Total area = 200 units² + 40 units²
Thus, the total area of the shape shown is 240 units².

Notes
If we want to calculate the total circumference, the length of the hypotenuse of the triangle must be determined through the Pythagorean Theorem.
