Drag the correct number of pieces to show how to find the area of the shaded figure in two different ways. pieces can be rotated to fit.

Check attachment for solution

Step-by-step explanation

1. For the first aspect,

We want to design, the area using exactly six pieces i.e. Pieces = 6

We should not that, the triangle at the edges are fixed, the cannot be replaced by rectangle

So, we have three triangle. So we are going to use the triangle at the edges.

Now we need to design the rectangle(required) which is 3 by 4 with three rectangle ( from the give shapes) so that it can complete using 6 pieces

We can use the horizontal 1 unit by 4 unit, we will make it vertical, so we need three of that to make it 3 by 4 as required by the area.

So, check attachment for better understanding

2. For the second aspect

We don't want the pieces to get to 6, i.e. pieces ≠ 6

Same as above, the triangle are fixed, so we already have 3 triangle,

So we need to design the rectangle (required) with less than 3 shapes

The required rectangle is 3 by 4

So, if we picked the 3 by 2 rectangle, it is in vertical direction, then, we rotate it to horizontal position, and we will need two of it to make it 3 by 4 .

So the total shape used is 5, then we used 5pieces here.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
