Answer:


A=(3√(55))/(2)

Explanation:

For a height h, a perimeter P, and an area A, use the following formula:


A=(1)/(4)h\sqrt{P^(2)-4h^(2) }

Next, replace the variables with the given values:


A=(1)/(4)(3)\sqrt{(16)^(2)-4(3)^(2) }

Solve the inside of the square root:


A=(1)/(4)(3)√(256-36)\\A=(1)/(4)(3)√(220)

Multiply outside of the square root:


A=(3)/(4)√(220)\\

Simplify the square root:


A=((3)/(4))2√(55)\\

Multiply outside of the square root once more:


A=(3)/(2)√(55)\\

Simplify:


A=(3√(55))/(2), or ≈ 11.12429773

I think the answer is 15 cuz if the height is 3; 3 on each side is 6 so 6-16=10 and 10 divided by 2 for the two others sides is 5… and 5x3=15
