What is the lateral area of the pyramid?

Aleks04 [339]

We have two triangles with base 9ft and height 12.3ft and two triangles with base 11ft and height 11.9ft.

The formula of an area of a triangle:

$A_\triangle=\dfrac{1}{2}bh$

Triangle #1:

b = 9ft and h = 12.3ft. Substitute:

$A_1=\dfrac{1}{2}(9)(12.3)=55.35ft^2$

Triangle #2:

b = 11ft and h = 11.9ft. Substitute:

$A_2=\dfrac{1}{2}(11)(11.9)=65.45ft^2$

The Lateral Area:

$L.A.=2A_1+2_A2\\\\L.A.=2(55.35)+2(65.45)=241.6\ ft^2$

<h3>Answer: B. 241.6 ft².</h3>
