5YRD 1 FT IS EQUAL TO 192 IN
Answer:
96250
Step-by-step explanation:
To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.
7x5x25x11x10=96250
hope i did it please mark as brainliest
<span>The first thing to know is that "an" and "a1" are names with subscripts and are and different from multiplication.
an = a1 + (n-1) d
add -a1 to both sides
an - a1 = a1 - a1 + (n-1) d
</span><span>an - a1 = (n-1) d
</span>d = (an-a1)/(n-1)
Steps:
Find the 2D area of the two triangles:
- multiply 6 x 8 and divide it by 2 (this is the bottom triangle.)
** don't use 10 because it is the hypotenuse.
- 6 x 8 = 48
- 48 / 2 = 24 (you will need to use this twice since there are 2 triangles)
Now find the 2D area of the three rectangles
- first you have to convert 4 yd to feet.
**1 yd = 3 ft
~4 yd = 12 ft
-now multiply 12 x 10
- 12 x 10 = 120ft (use this 3 times since there are 3 rectangles)
Now add all those together:
120 + 120 + 120 + 24 + 24 = 408
