use the quadratic formula, we must.
-13 +/- √(169 +48) / 2
-13 +/- √217 / 2
-13 +/- 14.73 / 2
(-13 + 14.73) / 2 = 0.865
(-13 - 14.73) / 2 = -13.865
the solutions, we have found.
helped, i hope i have.
Answer:

Step-by-step explanation: BECAUSE IN A PARALLELOGRAM OPPPOSITE SIDES ARE EQUAL SO IF THE PERIMETER IS 33.2 WE SHOULD SUBTRACT THAT NUMBER WITH 11.6*2 WHICH IS 23.2 SO 33.2-23.2 WHICH IS 10,SO 10/2 IS THE OTHER SIDE OF THE PARALLELOGRAMWHICH IS NOTHING BUT 5
Trapizoid area formula = (b1+b2)/2×h
rectangle formula =l×w
trapizoid 1: (12+16)/2×5
trapizoid 2: (12+16)/2×5
rectangle: 10×12
solve
t1 + t2:
(12+16)/2×5
28/2×5
14×5=70 +70=
140 ft^2
r: 10×12=120ft^2
140-120=20ft^2 of wood
