Check the picture below.
so the lateral area of the pyramid is really just the area of four triangles whose base is 10 and height is also 10, now, we're excluding the bottom because that's not lateral area.
Find the missing side length in the image below 12 18 and 10
1 answer:
The missing length of the right triangle is 13.41 inches.
<h3>How to find the side of a right triangle?</h3>A right angle triangle has one of its angles as 90 degrees.
The side length of a right triangle can be found using Pythagoras theorem.
Therefore,
c² = a² + b²
where
- c = hypotenuse
- a and b are the other legs.
Therefore,
x² = 18² - 12²
x² = 324 - 144
x² = 180
x = √180
x = 13.416407865
x = 13.41 inches
