Question

I don’t understand this?

Answer 1

Area of the triangle is 17.5 and the area of the square is 6. So, 17.5-6=11.5

Your answer is 11.5

Answer 2

11.5 cm²

Explanation:

We know that the triangle has a base of 3 + 4 = 7 and a height of 3 + 2 = 5. Therefore, the area of the triangle is 7 * 5 / 2 = 17.5. The area of the 3 by 2 rectangle is 3 * 2 = 6 so the shaded area is 17.5 - 6 = 11.5 square cm.
