The triangle <span>pyramid</span> is made up of 4 triangles.
------------------------------------
Formula:
------------------------------------
Area of triangle = 1/2 x base x height
------------------------------------
Area of the bottom triangle:
------------------------------------
Area = 1/2 x 9 x 7.8
Area = 35.1 yd²
------------------------------------
Area of the 3 side triangles:
------------------------------------
Area = 3 [ 1/2 x 9 x 10 ]
Area = 135 yd²
------------------------------------
Total Area:
------------------------------------
Total Area = 135 + 35.1
Total Area = 170.1 yd²
------------------------------------------------------------------------
Answer: Surface Area = 170.1 yd².
------------------------------------------------------------------------
These words are represented as homophones as they sound alike but have the different meanings.
This is true sometimes and false sometimes, depending on the numbers.
Draw the dilation image of the triangle with a center at the origin and a scale factor of two.
