Answer: RA, EJ, JT
Explanation:
When dealing with 3 dimensional figures, you must handle three concepts to analyze the spatial relationship of the lines. Those are:
- Perpendicular lines: it refers to lines that intersect each other at a 90° angle (right angle). This only can happen if the lines.
- Skew lines: it refers to lines that are not parallel but are in different planes and cannot not intersect each other.
- Parallel lines: are lines that are in the same plane but cannot intersect each other.
The given figure is a perfect model to understand what each one of those concepts mean.
Starting by the segment JA, you find that:
- The segments EH, QP, and TR are parallel to segment JA, because you can find a plane formed by JA and any of those segments, and yet JA will never intersect any of them.
- Segment JA is skewed respect segments QT, PR, QE, and PH, because they are in different planes.
- Segment JA is perpendicular to EJ, HA, JT and RA, because JAintersects any of them on a right angle.
Hence, the right choices are segments RA, EJ and JT
Perimeter (P) = 2L + 2w
68 = 2L + 2w
68 - 2L = 2w
2(34 - L) = 2(w)
34 - L = w
********************
Area (A) = L * w
240 = L (34 - L)
240 = 34L - L²
L² - 34L + 240 = 0
(L - 10)(L - 24) = 0
L = 10 or L = 24
w = 34 - L = 34 - 10 = 24 or w = 34 - 24 = 10
Answer: width = 10, length = 24 assuming length is bigger than the width
