Question

A city park has an architectural pillar in the shape of a triangular pyramid. The shape of the base of the pillar is an equilateral triangle. The dimensions of the shape of the pillar are as shown below.



The park plans to repaint the lateral area of the pillar. The area of the pillar that will be repainted is _______________ ft2.

Answer 1

area of a triangle is 1/2 base*height, so 1/2 your base=1 and your height is = to 14.
the area of one of the lateral surfaces would therefore be 14 ft^2
you then multiple 14 by 3 since you have three sides to the pillar.
total surface area to be painted would then equal 42 ft^2

Answer 2

so the answer is 42 ft^2

Answer 3

that's what i would put.
