You said that <u> A = 1/2 b h</u>

Multiply each side by 2 : 2A = b h

Divide each side by 'h' : <em>2A/h = b</em>

The answer appears to be choice 3 because it resembles an exponential function.
But I might be wrong.

Hope this helps :)

Answer:

5,000

Step-by-step explanation:

When a number is 5 or above, you would round up. When it is below 4 or below, you round down.

Since 5,182 the 1 is below 1, 5 would remain the same.

The area of the pentagon is 19 square units

The coordinates of the pentagon are given as:

$T = (1, 8)$

$E =(3, 8)$

$X =(6, 2)$

$A=(3, 2)$

$S = (1, 4)$

The area of the pentagon is then calculated using:

$Area = \frac 12|(x_1y_2+x_2y_3+x_3y_4+x_4y_5+x_5y_1) -(y_1x_2+y_2x_3+y_3x_4+y_4x_5+y_5x_1)|$

So, we have:

$Area = \frac 12|(1 \times 8 +3 \times 2+6\times2+3 \times 4 + 1 \times 8) -(8\times3+8\times6+2\times3+2\times1+4\times1)|$

Simplify the expressions in both brackets

$Area = \frac 12|46 -84|$

$Area = \frac 12|-38|$

Remove absolute bracket

$Area = \frac 12 \times 38$

$Area = 19$

Hence, the area of the pentagon is 19 square units
