Answer:

108 feet²

Step-by-step explanation:

Well we can just multiply the corresponding sides of Quadrilateral ABCD to fit Quadrilateral EFGH.

Line EF is 42 feet

Line FG is 18 feet

Line GH is 18 feet

Line HE is 30 feet

The perimeter of Quadrilateral EFGH is

30+18+18+42=

30+36+42=

66+42=

108 feet²

Answer:

min = 64.2m ; max = 86.2m

Step-by-step explanation:

$38.25m \leq AC < 38.35m
\\ 11.5deg \leq B < 12.5deg
\\ 19.5deg \leq D < 20.5deg$

$d_{min} = BC_{LB} - CD_{UB}
\\ \\ d_{min} = \frac{AC_{LB}}{tan(B)_{UB}} - \frac{AC_{UB}}{tan(D)_{LB}}
\\ \\ d_{min} = \frac{38.25}{tan(12.5)} - \frac{38.35}{tan(19.5)}
\\ \\ d_{min} = 64.2m (3sf)$

$d_{max} = BC_{UB} - CD_{LB}
\\ \\ d_{max} = \frac{AC_{UB}}{tan(B)_{LB}} - \frac{AC_{LB}}{tan(D)_{UB}}
\\ \\ d_{max} = \frac{38.35}{tan(11.5)} - \frac{38.25}{tan(20.5)}
\\ \\ d_{max} = 86.2m (3sf)$
