Find the lateral area for the pyramid with the equilateral base

A: 144 sq. units
B: 180 sq. units
C: 288 sq. units

Solution:

The given pyramid has 3 lateral triangular side

The figure is attached below

Base of triangle = 12 unit

Find the perpendicular

By Pythagoras theorem

Therefore,

Find the lateral surface area of 1 triangle

Thus, lateral surface area of 3 triangle is:

3 x 48 = 144

Thus lateral area for the pyramid with the equilateral base is 144 square units

y=mx+b

step-by-step explanation:

m slope, b y-intercept

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
