Answer:
29m²
Step-by-step explanation:
This shape contains 2 shapes that we are familiar with, a triangle and a square. We need to know how to work out the area of a triangle and a rectangle so
→ Area of a rectangle = Length × Width
→ Area of a triangle = 0.5 × Base × Height
In this question we are asked to find the area of shaded region so the first step would be to work out the area of rectangle. Then work out the area of the triangle. Finally minus the 2 answers from each other.
→ First step would be to work out the area of rectangle
Area of a rectangle = Length × Width
Area of a rectangle = 7 × 5 = 35m²
→ Then work out the area of the triangle.
Area of a triangle = 0.5 × Base × Height
Area of a triangle = 0.5 × 4 × 3
Area of a triangle = 6m²
→ Finally minus the 2 answers from each other
35m² - 6m² = 29m²
The area of the shaded region is 29m²
