Answer 1

Answer:

The Answer is 168ft I took the test and got it right have a great day.

Step-by-step explanation:

Answer 2

Answer: (1) D   (2) C    (3) 168 ft²

Step-by-step explanation:

1)

The length of the stamp is 8 - 6 = 2

The width of the stamp is 5 - 3 = 2

A = length x width

A = 2 x 2

   = 4

Answer: D

2)

Figure I is a Rectangle and a Triangle

Rectangle: A = length x width

                      =   3 x 3

                      =   9

$\text{Triangle}:A=\dfrac{b\times h}{2}\\\\\\.\qquad \qquad \quad = \dfrac{3\times 2}{2}\\\\\\.\qquad \qquad \quad = 3$

Area of Rectangle + Triangle = 9 + 3  =  12

Figure 2 is a Trapezoid and a Triangle

$\text{Trapezoid}:A=\dfrac{b_1+b_2}{2}\times h\\\\\\.\qquad \qquad \qquad =\dfrac{4+2}{2}\times 4\\\\\\.\qquad \qquad \qquad =3\times 4\\\\\\.\qquad \qquad \quad = 12\\\\\\\text{Triangle}:A=\dfrac{b\times h}{2}\\\\\\.\qquad \qquad \quad =\dfrac{4\times 2}{2}\\\\\\.\qquad \qquad \quad =4$

Area of Trapezoid + Triangle = 12 + 4 = 16

Figure III is Rectangle and a Triangle

Rectangle: A = length x width

                      = 3 x 5

                      = 15

$\text{Triangle}: A=\dfrac{b\times h}{2}\\\\\\.\qquad \qquad \quad =\dfrac{5\times 3}{2}\\\\\\.\qquad \qquad \quad =7.5$

Area of Rectangle + Triangle = 15 + 7.5 = 22.5

The order from least to greatest is: I, II, III

Answer: C

3)

A = length x width

   = 14 x 12

  = 168
