Answer:
The smaller board would be 2.75 feet and the longer one would be 10.25 feet.
Step-by-step explanation:
In order to find this, assume the shorter board is equal to x. Next, we would know that the longer board would be equal to x + 7.5. Using these two assumptions, we can add the lengths together, set equal to 13 and then solve for x.
x + (x + 7.5) = 13
2x + 7.5 = 13
2x = 5.5
x = 2.75
Now that we have the length of the shorter board, we can add 7.5 to it to get the larger one.
2.75 + 7.5 = 10.25
You have to find the area of each face and add them all together. You also need to find the unknown side which is indicated in the picture i attached.

Step-by-step explanation:
A. albatross - blue jay = 3 1/2 - 39/100
================== (3*2)+1/2 - 39/100
================== 7/2 - 39/100
================== 311/100
================== 3.11
b. Golden eagle - seagull = 2 1/4 - 11/5
======================= (2*4)+1/4 - 11/5
======================= 9/4 - 11/5
======================= 1/20
======================= 0.05
