in rectangle ABCD, point lies halfway between sides a b and c d is halfway between sides AD and BC. is a beagle's 9 and BC equals 10, what is the area of the Shaded region?

The area of the shaded region is 38.50 square units

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of the shaded region is equal to the area of triangle ABE plus the area of triangle CDE

Remember that the area of triangle is equal to

where

b is the base

h is the height

Find the area of triangle ABE

substitute the values

Find the area of triangle CDE

substitute the values

Find the area of the shaded region

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
