Sum of interior angles of a quadrilateral is 360°
- 110° + 130° + x + x - 3° = 360°
- 2x = 360° - 237°
- 2x = 123°
- x = 61.5°

Sum of interior angles of a hexagon is 180°*(6 - 2) = 720°
- 2*90° + 2x + 2(x + 22°) = 720°
- 90° + x + x + 22° = 360°
- 2x = 360° - 112°
- 2x = 248°
- x = 124°

Interior angles of a given pentagon are all marked as congruent, so the exterior angles are congruent too.
Sum of exterior angles is 360°.
Answer:
1/6 squared feet or 0.17 squared feet
Step-by-step explanation:
Since it's a paper, we assume it is a rectangle.
Use the formula for area of a rectangle. A= lw
l is the length and w is the width.
The width is 2/3 feet and the length is 1/4 feet.
Substitute w = 2/3 and l=1/4 into the equation for area of a rectangle.
A = lw
A = (1/4)(2/3) Multiply both numerators, then both denominators
A = 2/12 Simplify. Top and bottom are divisible by 2
A = 1/6
A ≈ 0.17 Rounded to two decimal places
When you multiply two numbers with units, the answer's unit becomes the squared unit.
Therefore the area of her paper is 1/6 squared feet, or 0.17 squared feet.
