When finding the surface area of the rectangular pyramid, what dimension will be used to find the height of the triangular sides on the front of it on the bottom, we had 66 m on the right side on the bottom we had 2 m on the right side for the length we have 9 m and on the left side it’s pointing to the middle the middle line and it’s 8.8 m so what is the answer?
To find the height of the triangular sides on the front of the rectangular pyramid, you can use the Pythagorean theorem.
First, calculate the length of the base of the triangle:
Base = (8.8 m + 9 m) / 2 = 8.9 m
Next, calculate the hypotenuse of the triangle (diagonal of the rectangle):
Hypotenuse = √(8.8^2 + 9^2) ≈ √(77.44 + 81) ≈ √158.44 ≈ 12.6 m
Now, you can find the height of the triangular sides by using the Pythagorean theorem in the right triangle formed by half of the base (4.45 m) and the hypotenuse (12.6 m):
Height = √(12.6^2 - 4.45^2) ≈ √(158.44 - 19.8) ≈ √138.64 ≈ 11.8 m
Therefore, the height of the triangular sides on the front of the rectangular pyramid is approximately 11.8 meters.
