Answer:
x = 9, y = 27
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
=
( cross- multiply )
12(x - 1) = 96 ( divide both sides by 12 )
x - 1 = 8 ( add 1 to both sides )
x = 9
Also
=
( cross- multiply )
12(y + 1) = 336 ( divide both sides by 12 )
y + 1 = 28 ( subtract 1 from both sides )
y = 27
A square has four sides which all have the same length.
So if we call the length of each side of the square 'a'
The sum of length of all the sides (the perimeter) will be ,
a + a + a + a = 4a
Now let's equal this to the perimeter to find the length of each side 'a'

So the length of each side of the square is 2 cm
To find area of a square we multiply the length of its two sides
So,

is the area of the square,

The answer :
If you put 2 points on a graph paper and connect them, you can find the midpoint pretty easily
So first, you would multiply 10 times 10 to get 100 square feet. And since there are 10 exam rooms, you multiply 100 to 10 and you would get 1000. Then to calculate the waiting area, you multiply 20 times 15 to get 300 square feet. Then the office area would be 25 times 20 which is 500. So you would add up 1000+300+500. The answer comes out as 1800 square feet. Hope this helped! Good luck!
