Given:

The figure of a regular polygon.

To find:

The area of the regular polygon.

Solution:

From the given figure it is clear that the regular polygon has 4 vertices. It means, it is a square.

Distance between the center and the vertex is 7 yd. So, the diagonal of the square is

d=7+7

d=14 yd

We know that, area of a square is

A=\dfrac{1}{2}d^2

Putting d=14 in the above formula, we get

A=\dfrac{1}{2}(14)^2

A=\dfrac{1}{2}(196)

A=98

Therefore, the area of the regular polygon is 98 sq. yd.

In triangle ABC below, sinC=h/a and sinA=h/c. Which of the following combines the two sine ratios into one equation?
LenaWriter [7]

We know:

sin(C)=\frac{h}{a}

and

sin(A)=\frac{h}{c}


These expressions have an h term in common. We can combine them if we can find forms of the expressions in terms of h:

h=a(sin(C))

h=c(sin(A))


Now, because h=h (by the reflexive property), we can write:


a(sin(C))=c(sin(A))


This is our answer, A.
