<span>Changing the grouping of the addends should not change the sum, according to the associative property of addition. You might group them differently with (50 + 3) + 47, so that you have 50 + (3 + 47). You might not regroup them with (16 + 4) + 5 rather than 16 + (4 + 5).</span>

Answer:
Step-by-step explanation:
The perimeter is 28".
The total length of three sides of the square = 28-5-5 = 18", so the side length of the square is 18/3 = 6".
The area of the triangle is ½(6)(4) = 12 square inches.
The area of the square is 6² = 36 square inches.
Total area = 12+36 = 48 square inches.
