The width is doubled, and so is the length.
75' x 75' lawn:
W * L = $20
150' x 150' lawn:
2W * 2L
= 4( W * L ) = 4($20)
4 times as much area = 4 times as much cost = $80

$80
a 75*75 ft lawn is 1/4 the size of a 150*150 lawn, so the charge for the larger lawn is 4 times the charge of the smaller, or 4*20 = 80 dollars

(150)(150) = (2)(75)(2)(75) = 4(75(75 Therefore the charge for a 150 by 150 is 4 times charge for 75 by 75 so charge = 4*20 =$80.

So, the 75*75 ft yard is 5625 square feet. So he charges $20/5625 sqr feet or about $.00355555/ sq ft.
The 150*150 lawn is 22500 sq ft so he would charge $22500*.0035555 for that lawn or about $80..

it will be 150^2/75^2 *20=$80

First, you find the total number of square feet (i.e. 75 X 75).
-------------> 5,625 square feet
Then, you divide the 20 total dollars that he charged by the total number of square feet to find the amount per square foot. (i.e. 20/5625)
-------------> $.0035555556
Now, find the total square feet of the 150ft by 150ft lawn.
-------------> 22500 square feet
Lastly, multiply the total number of square feet by Yo's fee per square foot (i.e. 22500 X .0035555556).
------------> Your answer is 80. Put this in the correct terms and you get $80.
Hope this helps!

$80...
75 x 75 = 5625 sqft
$20 / 5625 = .00356 $/sqft
150 x 150 = 22500 sqft
22500 sqft x .00356 $/sqft = $80.00

You should watch "Animal Face-off" on the Discovery Channel. Here is a link where you can match up some animals. My favorite episode has been Elephant vs. Rhino....there is just no way a human could survive an attack by a Rhino....

he charges;
75ft x 75ft = $20.
5600 sqft= $20.
therefore 1sqft= $20/5600
150ft x 150ft=22500sqft
so for 22500sqft he will charge ;
$20/5600 x 22500 = $80.35
hope this helps.

$20 for (75x75) square feet.
for 150x150 sq ft should be
= (150x150)/(75x75)x$20
=$80
