3 fish are left because 4 - 1 = 3 =) I hopes this helps lol!
Hey there!

I attached an image to make this a lot easier to understand.
I split up the rectangle into four triangles and one rectangle. We are going to find the area of each one individually then add them together.
Also note that there are two pairs of congruent triangles so they will have the same area.
The top and bottom triangles have heights of 2 and lengths of 5. This means their areas are each 5.
The left and right triangles have heights of 6 and lengths of 3. This means their areas are each 9.
The rectangle has a height of 6 and a length of 2. This means its area is 12.
Now we can add together all the areas of the individual pieces.
5 + 5 + 9 + 9 + 12 = 40
So the area is 40 square units.
Hope this helps!
Answer:
72
Step-by-step explanation:
<em>Since the ratio of blue jays to robin's was 6 to 7 then if there were 84 robins how many blue jays were there.</em>
<em>6 to 7 can also be express as 6/7</em>
<em>Thus, we can set up a proportion</em>
<em>6/7 = x/84</em>
<em>Now, we have to solve for x</em>
<em>x = 72</em>
<em>Hence, if there were 84 robin there would be 72 blue jays.</em>

Answer:
Perimeter: 60.6cm
Area: 212.3cm
Step-by-step explanation:
When calulating the perimeter, you are adding the length of all the sides together. Since the figure is a rectangle, two two pairs of sides will be different lengths. Solving is as follows:
P= 11+11+19.3+19.3 or P=11(2)+19.3(2) =60.6
With area, you need the total amount of mass, so you would multiply two sides. In this case, the two are 11cm and 19.3cm.
A= 11(19.3)cm =212.3
