We are given with a regular 15-gon with a perimeter of 90 meters. In this case, side length is equal to 90/15 or 6 m. The angle inside the center is 360/15 or 24 degrees. We determine the area of each triangle (15 of them) and just multiply by 15 to get the total area. The height of each triangle is tan (12) = 3/ h where h is equal to 14.11 meters. Hence the area is 0.5*14.11*6*15 or equal to 635.13 meters.

Step-by-step explanation:
here,
area of parallelogram =base ×height
so,
base is given 10 cm and height is given 7 cm
Now
base ×heights
10×7

The answer I got is $24 7/8. Hope this helps
Answer:
56
Step-by-step explanation:
8*(8+6)
8*14=112
112/2=56
Basically, you do 2/3-5/6
2/3-5/6=4/6-5/6=-1/6
