No, a parallelogram is not a rectangle. meaning it has a completely different area formula, I know it sucks.
Formula: base × height
I don't use feet and inches. sorry I couldn't provide with to much help.
Use distributive property to solve.
2x(5x+3) + 7(5x+3)
1. distribute
2x•5x = 10x^2
2x•3= 6x
10x^2+6x
7•5x = 35x
7•3= 21
35x+21
2. combine like terms
10x^2+6x+35x+21
10x^+ 41x +21 [final answer]

Answer:
4.84 square inches
Step-by-step explanation:
To first find the missing angle, 180 - (50+47) = 83
Then I used the formula Area = (a x b x sinc) / 2
Plug in side one for a, side two for b, and the angle between for c
