Find the area of the regular polygon

Mathematics
1 answer:
Vikki [24]2 years ago
6 0

Answer:

162m²

Step-by-step explanation:

distance from corner to center = 1/2 of the diagonal

all sides are equal, and this has 4 sides, so it is a square

9m = 1/2 of diagonal

multiply both sides by 2 to isolate the diagonal

18m = diagonal

area of square = length²

length * √2 = diagonal

given the diagonal, we can find the length and then the area

length * √2 = diagonal

divide both sides by √2 to find the length

18m/√2 = length ≈12.7

square the length to find the area

area = 162 m²

Let's solve for the other leg length
a^2 + 21^2 = 42^2
a^2 + 441 = 1764
subtract 441 from both sides
a^2 = 1323
take the square root of both sides
a = sqrt.(1323)
a = 21 sqrt.(3)

The correct answer is C.) The length of the remaining leg is 21 sqrt.(3).

Hope this helps

taurus [48]

Answer:

(10, -3)

Step-by-step explanation:

-\frac{7}{2}x+32=\frac{4}{5}x-11 \\ \\ -35x+320=8x-110 \\ \\ -43x=-430 \\ \\ x=10 \\ \\ \therefore y=-\frac{7}{2}(10)+32=-3
