Write an expression for the area of square 5 by combining the areas of the four triangles and the one square.

2ab + c²

Step-by-step explanation:

Please find attached a diagram of square 5

Area of a triangle = 1/2 x ( base x height)

(1/2 x (a xb) ) x 4 = 2ab

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

a² + b² = c²

a² + 2ab+ b² = 2ab + c²

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
