So here is what we have
12 is what we need
out of the 84 we have
so...
12/84= .1428571429
and lets check our work
.1428571429 X 84 = 12
now lets convert it to a percent
.1428571429 X 100 = 14.28571429%
so the answer is
14.28571429%
Since they mowed

of the lawn in two equal parts, we need to split the pieces that were mowed into two equal groups. We know that in total they mowed 8 out of the total 9 pieces of lawn, so two equal groups that make 8 would be of size 4, since

. Then they each mowed

of the lawn.
5/6 can be simplified to 0.83. 10.83*18=194.94 square feet. 1,800 minus 194.94 is 1605.06 more square feet required
To answer this question, you should draw it out- see the attached picture for the example. All the side lengths are labeled. You can then use the area of a trapezoid formula to find the total area.
A=1/2 (b1 + b2)h
You can see the substitution for each value in the work shown in the picture.
