Find the area of a regular polygon that has 8 sides and each side is 6.8 units long.

Formula for the area of a regular polygon. ... The number of square units it takes to completely fill a regular polygon. Four different ways to calculate the area are given, with a formula for each. Try this Drag ... Alter the number of sides. ... If you know the apothem, or inradius, (the perpendicular distance from center to a side.

Missing: 6.8 ‎| Must include: 6.8

Step-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
