Answer:
15 units²
Step-by-step explanation:
Since there is no specific formula to work the area of this shape, we have to use the area of a square and the area of a triangle. We can see that the shape is composed of 2 regular shapes that we know the area's for hence why I put we have to use the area of a square and the area of a triangle.
Area of rectangle = 3 × 3 = 9
But we have a base length for the triangle as well as the triangle so we have to minus the square length from the overall length to find the triangle base length so 7 - 3 = 4
Area of a triangle = 1 / 2 × Base × Height
Area of a triangle = 1 / 2 × 4 × 3
Area of triangle = 6
Now we add the overall areas together to get the final area of the whole shape so
Area of the triangle + Area of the square = Total Area
6 + 9 = 15
So the answer is 15 units²
