9x + 4= 5x + 20 (alternate interior angles)
9x-5x =20-4
4x = 16
x= 16/4
x= 4
Your answer would be: <em>693.</em>
Explanation:
When finding the area in a problem use <em>L×W×H</em>.
That being said, you now have to multiply the <em>L×W×H</em> (7x9x11)
7 × 9 × 11 = <em>693</em>
So the answer would be <em>693</em> because, if you are finding an area you use <em>L×W×H</em> to find your area.
The perimeter would be about 34.4 because if you choose the bottom side to be ten, by multiplying 35 by 2 to get 70 you can divide by 10 to get 7. Since you know the height and width, you can use pythagorean theorem, a^2 + b^2 = c^2. Plug in the numbers you have 10^2+7^2=c^2. c^2=149, so if you square root 149 you will get a irrational number but when rounded you get 12.2- so that is one side multiply by 2 and get 24.4- and add 10 to get 34.4
EG and FH are diagonals of the rhombus and the bisect each other at the centre to for a righ angle triangle with the side of the rhombus as the hypothenus.
By pythagoras theorem,
