What is the surface area of the regular pyramid given below? the base length is 9 , base width is 9 , and the height is 7

Total Surface Area of the given regular pyramid = 153 units²

Step-by-step explanation:

Base length of the regular pyramid, l  = 9 units

Base width of the regular pyramid, w = 9 units

Height of the regular pyramid, h = 7 units

Perimeter of base = 3 × 9

                              = 27 units

Hence, Total Surface Area of the given regular pyramid = 153 units²

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.
