We have a bunch of rectangles making up the lateral sides of this figure. They have side length 12 and height 13.
So the area of one rectangle is 12 x 13 = 156.
We have 6 of these rectangles, so our lateral area is 6(156) = 936.
The total surface area requires that we include the area of the base. To find the area of a regular polygon we take half of the product of the apothem and perimeter.
A = (1/2)*a*p
The apothem is given to be 10.39,
and the perimeter is fairly easy to calculate:
With the side length being 12, the perimeter is then 6(12) = 72.
So then the area of our base is (1/2)*10.39*72 = 374.04
So then the total surface area is the (base area) + (lateral area),
374.04 + 936 = 1310.04
Answer:
20+56 or basically 76
Step-by-step explanation:
Just multiply -8 to -2.5 and -7.
I believe the equation would be
160+0.2y
Because 160 deer and you round the 20% into a decimal point.
Answer:
13 petunias
Step-by-step explanation:
13x7=91
9x8=72
add them and you get 163
