Answer:
It should be the second one 4,18,6
Step-by-step explanation:
Let me know if that is right . . .
Hope this helps!
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
Jeff is correct because:
2 sides of a triangle must always be longer than the other side, so:
12+8>19
19+8>12
12+19>8
Since all of them are true, Jeff is correct
Answer:
100 - 20 = 80 Length Of the Garden
Step-by-step explanation:
So You Can do 20 Ft Minus 100 Because 100 is the Total so Heres a Graph To Show You
Total= 100 Ft
Width= 20
Length=?
Total - Width = Length
100 - 20 = 80 Length Of the Garden
