Question

3. Find the area of pentagon ABCDE in which BL I AC. DM 1 AC
and EN 1 AC such that AC = 18 cm, AM = 14 cm. AN = 6 cm.
BL = 4 cm. DM = 12 cm and EN = 9 cm​

Answer 1

i will no tell the answer but i can tell how to calculate

Start with the side length and apothem. This method works for regular pentagons, with five equal sides. Besides the side length, you'll need the "apothem" of the pentagon. The apothem is the line from the center of the pentagon to a side, intersecting the side at a 90º right angle.

Don't confuse the apothem with the radius, which touches a corner (vertex) instead of a midpoint. If you only know the side length and radius, skip down to the next method instead.

We'll use an example pentagon with side length 3 units and apothem 2 units.

now do it your self

all the best
