The area of the shaded region is 9cm²
The formula for calculating the area of a triangle is expressed as;
Area = 1/2bh
Such that;
- b is the base
- h is the height
Then, area of the triangle is = 6 ×6/2
Area = 18cm²
Now, area of a square is s²
Area of the square = 3² = 9cm²
Now, area of the shaded area;
= Area of triangle - area of square
= 18 - 9
= 9cm²
