# How to find a sloping edge of a rectangular based pyramid? The rectangular based has length 4.8m and width 3m and the height of the pyramid is 4m .

##### 1 Answer

#### Explanation:

Determine the center point of the rectangular base:

The crossing point of the two lines= centre point of the rectangle.

This centre point is also the bottom of the perpendicular height of 4m given.

Draw a line from the corner of the rectangle to the centre of the rectangle.

So: In the horizontal right triangle= adjacent side=1.5m and opposite.side=2.4m

With Pythagoras:

hypotenuse

hypotenuse

hypotenuse

Opposite side given

So: In the vertical right triangle the hypotenuse = slope of pyramid
