Give an example of an addition problem in which you would and would not group the addends differently to add
madam [21]
<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>

No one answered it last time :(
azamat

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.
