1.      The name of the quadrangle is Beverly Hills Quadrangle. 

2.      The adjacent quadrangles: Canoga Park, Van Nuys, Burbank, Topanga, Hollywood, Pacific Ocean, Venice, and Inglewood. 

3.      This quadrangle was first created in 1966.

4.      Datum are: North American Datum of 1927 and North American Datum of 1983

5.      The scale of this quadrangle is 1:24,000

6.         a) 5 × 24,000 = 120,000 cm
        120,000 ÷ 100 = 1,200 m
        ∴ 5 cm on the map = 1,200 m on the ground
   b) 5 × 24,000 = 120,000 in
        120,000 ÷ 12 = 10,000 ft
        10,000 ÷ 5,280 = 1.8939 miles
        ∴ 5 in on the map = 1.8939 miles on the ground
   c) 1 ÷ 24,000 = 0.000041667 miles
        0.000041667 × 5,280 = 0.2200 ft
        0.2200 × 12 = 2.64 in
        ∴ 1 mile on the ground = 2.64 in on the map
   d) 1 ÷ 240,000 = 0.000041667 km
        0.000041667 × 3 = 0.000125001 km
        0.000125001 × 1000 = 0.125001 m
        0.125001 × 100 = 12.5001 cm
        ∴ 3 km on the ground = 12.5 cm on the map

7.       The contour interval is 20 ft

8.         a) Latitude:
        11.2 cm/14.3 cm = y'/2.5'
        minutes = (11.2 ÷ 14.3) × 2.5 = 1.958'
        seconds = 0.958' × 60 = 57.48"
        minutes and seconds = 2' + 1' + 30" + 57" = 3' 87" = 4' 27"
        decimal degrees = 34 + (4 ÷ 60) + (27 ÷ 3600) = 34.07417
        Longitude:
        5.9 cm/12 cm = y'/2.5'
        minutes = (5.9 ÷ 12) × 2.5 = 1.229'
        seconds = 0.229' × 60 = 13.74"
        minutes and seconds = 25' + 1' + 14" = 26' 14"
        decimal degrees = 118 + (26 ÷ 60) + (14 ÷ 3600) = 118.4372
        ∴ the Public Affairs Building: 34° 4' 27" N, 118° 26' 14" W or +34.0741, -    118.4372
   b) Latitude:
        2.6 cm/14.3 cm = y'/2.5'
        minutes = (2.6 ÷ 14.3) × 2.5 = 0.4545'
        seconds = 0.4545' × 60 = 27.27"
        minutes and seconds = 0' 27"
        decimal degrees = 34 + (27 ÷ 3600) = 34.0075
        Longitude:
        11 cm/12 cm = y'/2.5'
        minutes = (11/12) × 2.5 = 2.29167'
        seconds = 0.29167' × 60 = 17.5002"
        minutes and seconds = 27' + 2' + 30" + 18" = 29' 48"
        decimal degrees = 118 + (29 ÷ 60) + (48 ÷ 3600) = 118.4967
        ∴ the tip of Santa Monica pier: 34° 0' 27" N, 118° 29' 48" W or +34.0075, -118.4967
   c) Latitude:
        13.2 cm/14.3 cm = y'/2.5'
        minutes = (13.2 ÷ 14.3) × 2.5 = 2.3077'
        seconds = 0.3077' × 60 = 18.462"
        minutes and seconds = 5' + 2' + 18" = 7' 18"
        decimal degrees = 34 + (7 ÷ 60) + (18 ÷ 3600) = 34.1217
        Longitude:
        10.1 cm/12 cm = y'/2.5'
        minutes = (10.1 ÷ 12) × 2.5 = 2.10417'
        seconds = 0.10417' × 60 = 6.2502"
        minutes and seconds = 22' + 2'+ 30" + 6" = 24' 36"
        decimal degrees = 118 + (24 ÷ 60) + (36 ÷ 3600) = 118.41
        ∴ the Upper Franklin Canyon Reservoir: 34° 7' 18" N, 118° 24' 36" W or +34.1217, -118.41

9.         a) Greystone Mansion: 660 ft or 660 × 0.305 = 201.3 m
   b) Woodlawn Cemetery: 140 ft or 140 × 0.305 = 42.7 m
   c) Crestwood Hills Park: 680 ft or 680 × 0.305 = 207.4 m

10.   UTM zone 11

11.  UTM coordinates are for the lower corner of the map: 362000m E, and 3763000m N.

12.   Each square in this map obtains 1,000 square meters.

13.   

14.  The magnetic declination is +14°.

15.  The water flows from the north to the south because the elevation in the north is higher than in the elevation in the south.
