If AB=BC=CD what is the area of the green region? please show full workings ​
Romashka-Z-Leto [24]

The area of the green region is of:

9 units².

<h3>How to obtain the area of the green region?</h3>

The base is composed by three equal segments, hence their lengths are given as follows:

AB = BC = CD = 9/3 = 3.

The heights are given as follows:

  • B = 2.
  • C = 4.
  • D = 6.

As they are proportional.

The green region is composed by:

  • A rectangle of dimensions 3 and 2.
  • A right triangle of sides 3 and 2.

The area of the rectangle is given by the multiplication of the dimensions, hence:

Ar = 3 x 2 = 6 units².

The area of the triangle is given by half the multiplication of the dimensions, hence:

At = 0.5 x 3 x 2 = 3 units².

Then the area of the green region is given by:

A = Ar + At = 6 + 3 = 9 units².

2. If you buy a new mint-condition action figure, worth $106 and
MaRussiya [10]

Answer:

$82.68

Step-by-step explanation:

Original price of mint - $106

Percent discount = 22%

Discount price = 22/100 * 106

Discount price = 0.22 * 106

Discount price  = $23.32

New value = Original price - discount price

New value = 106 - 23.32

New value  = 82.68

Hence the new value of the figure will be $82.68
