Answer:75 children

Step-by-step explanation: Let the number of children will be x, so the number of adults will be 215-x

Making equation: 3x+5(215-x)=925

3x+1075-5x=925

-2x=925-1075

-2x=-150

x=75

Find the area of the figure. Round your answer to the nearest tenth.
Ulleksa [173]

Answer:

Area of the parallelogram= 10\sqrt{3} m^2

Step-by-step explanation:

Area of a parallelogram = Length * Perpendicular height

To find the perpendicular height of the parallelogram:

Using given angle 60° in the triangle.

sin(60)=\frac{Perpendicular}{Hypotenuse}

\frac{\sqrt{3} }{2}=\frac{Perpendicular}{4}  \\\\Perpendicular=\frac{4\sqrt{3} }{2} \\\\Perpendicular=2\sqrt{3} m

Area of the Parallelogram:

                                           =5*2\sqrt{3}\\\\ =10\sqrt{3}

Area of the parallelogram= 10\sqrt{3} m^2
