Can u guys help me with this it is Surface Area of a Rectangle thank u

1. 192 cm Squared

2. 76 ft Squared

3. 450 yd Squared

4. 510 in Squared

5. 204 mm Squared

6. 194 cm Squared

Step-by-step explanation:

1.  192 cm Squared

2 x 8 x 4 + 8 x 8 x 2

64 + 128 = 192

2. 76 ft Squared

1 x 4 x 2 + 1 x 7 x 2 + 4 x 7 x 2

8 + 12 + 56 = 76

3. 450 yd Squared

15 x 10 x 2 + 15 x 3 x 2 + 10 x 3 x 2

300 + 90 + 60 = 450

4.  510 in Squared

9 x 15 x 2 + 9 x 5 x 2 + 5 x 15 x 2

270 + 90 + 150 = 510

5. 204 mm Squared

1 x 9.3 x 2 + 1 x 9 x 2 + 9 x 9.3 x 2

18.6 + 18 + 167.4 = 204

6. 194 cm Squared

3 x 12 x 2 + 12 x 4 x 2 + 3 x 4 x 2

72 + 96 + 24 = 194

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
