a triangular lot in a park has a base with a measure that is 4 more than twice the height of the lot. the area of the lot is 99 square feet. since the area of a triangle is found by using the formula a=1/2 bh, the area for this lot can be represented by the equation 99=1/2(2h+4)h, where h represents the height of the triangle.
what is the height of the lot?

Simplify the equation they gave you: 99 = 1/2*(2h + 4)*h; first multiply

99 = (h + 2)*h

99 = h² + 2h; subtract h² + 2h from both sides

99 - h² - 2h = 0; rearrange

-h² - 2h + 99 = 0; factor

(-h + 9)(h + 11) = 0; set each factor equal to 0

-h + 9 = 0 → h = 9           h + 11 = 0 → h = -11

The value of h has to be positive so lets go with 9. Plug it ito the equation to make sure.

99 = 1/2*(2(9) + 4)*9

99 = 1/2*22*9

99 = 99; that means that the answer was right → 9 is the height

I hope this helps you!

Step-by-step explanation:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
