Triangle A- p, q
Triangle B- r, s
The dimensions of triangle A are twice the dimensions of Triangle B. The area of triangle B is 18cm2
What is the area of triangle A?
Since the dimensions of triangle A are twice the dimensions of triangle B, we can say that p = 2r and q = 2s.
The area of a triangle can be calculated using the formula: Area = (1/2) * base * height.
For triangle B:
Area_B = (1/2) * r * s
18 = (1/2) * r * s
36 = r * s
Now, for triangle A:
Area_A = (1/2) * p * q
Area_A = (1/2) * (2r) * (2s)
Area_A = 4 * (1/2) * r * s
Area_A = 4 * 18
Area_A = 72
Therefore, the area of triangle A is 72 cm^2.
