  • Answer:

<em>86.20 ft²</em>

  • Step-by-step explanation:

<em>Hi there !</em>

<em>A = A₁ + A₂</em>

<em>A₁ =semicircle</em>

<em>A₁ = πr²/2</em>

<em>r = d/2 = 6.4ft/2 = 3.2 ft</em>

<em>A₁ = 3.14×(3.2ft)²/2 ≈ 32.15 ft²</em>

<em />

<em>A₂ =  trapezium</em>

<em>A₂ = (b + B)×h/2</em>

<em>A₂ = (5.1ft + 6.4ft)×9.4ft/2 = 54.05 ft²</em>

<em />

<em>A = 32.15 ft² + 54.05 ft² = 86.20 ft²</em>

<em>Good luck !</em>

What is the length of LINE GH?<br> And please explain why thank you:
lesya692 [45]

co-ordinates of point G are (1,2)

co-ordinates of point H are (3,-3)

so, by distance formula :

\sqrt{( {x1 - x1})^{2} + ( {y1 - y2})^{2}  }  \\  =  \sqrt{( {1- 3})^{2} + ( {2 - ( - 3)})^{2}  }  \\   \sqrt{( { - 2})^{2} + ( {2  + 3})^{2}  }  \\  \sqrt{( { - 2})^{2} + ( {5})^{2}  }  \\   \sqrt{4 + 25}  \\  \sqrt{29}

so, it is root(29) or 5.38 units
