Find the surface area of a pentagon-based pyramid with slant height of 11 m.

Ronch [10]

Answer:

108.75 square meter.

Step-by-step explanation:

<h3>Surface area of pentagon based pyramid:</h3>

$\sf \boxed{\text{\bf Surface area of pentagonal pyramid = $ \bf \dfrac{5}{2}*b*(a + s)$}}$

Here, b is the base length of the pyramid. b = 3 m

a is the apothem of the pyramid. a = 3.5 m

s is the slant height of the pyramid. s = 11 m

$\sf Surface \ area = \dfrac{5}{2}*3*(11 + 3.5)$

$\sf = \dfrac{5}{2}*3*14.5\\\\ = 108.75 \ m^2$
