The parallelogram below will be cut into two congruent triangles. What is the area of one of the triangles?

Area of each triangle = 35 cm²

Step-by-step explanation:

Given:

Base of parallelogram = 14 cm

Height of parallelogram = 5 cm

Two equal congruent triangles

Find:

Area of each triangle

Computation:

We know that equal congruent triangles have equal area

So,

Area of each triangle = Area of parallelogram / 2

Area of each triangle = Area of parallelogram / 2

Area of each triangle = [B x H] / 2

Area of each triangle = [14 x 5] / 2

Area of each triangle = [70] / 2

Area of each triangle = 35 cm²

the answer is 5/3x+7/5y+7

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.
