- 3| 4.5 - 2| - 5 |-1.5 -(- 3)| =
- 3 |2.5| -5 |-1.5 + 3| =
- 3*2.5 - 5|1.5| =
- 7.5 - 5*1.5 =
- 7.5 - 7.5=
- 0
The correct answer is -3

<em>≈ 63.30 ft²</em>
- Step-by-step explanation:
<em>Heron formula</em>
<em>A = √p(p - a)(p - b)(p - c)</em>
<em>a = 9 ; b = 15 ; c = 20</em>
<em>p = (a + b + c)/2 = (9 + 15 + 20)/2 = 44/2 = 22</em>
<em>A = √22(22-9)(22-15)(22-20)</em>
<em>= √22×13×7×2</em>
<em>= √4004</em>
<em>≈ 63,27</em>
<em>≈ 63.30 ft²</em>
