Find the height, H, of the triangle shown

1 answer:

8 0

The first thing you should do is use the fact that the area of the triangle is:
A = b * h * (1/2).
From there you clear the height as a function of "c"
Then you will have a polynomial division which you must make to find the height of the triangle.
I attach the solution.

The length of a rectangle is one foot more than twice its width. If the area of the rectangle is 300ft2, find the dimensions of

Gemiola [76]

Answer:

12 ft x 25 ft

Step-by-step explanation:

If L is the length and W is the width:

L = 2W + 1

300 = LW

Substitute:

300 = (2W + 1) W

300 = 2W² + W

0 = 2W² + W − 300

0 = (2W + 25) (W − 12)

W = 12

L = 2W + 1

L = 25

The rectangle is 12 feet wide and 25 feet long.
