We can write the following system of equations:

, where is the number of chickens and is the number of sheep.

Multiply the second equation by and add both equations to solve for :

.

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36
