Answer:
Step-by-step explanation:
To calculate an area of a rectangle, use the formula A=l*w. We know the width is 7m greater than the length. So w = 7 + x. So the area is A= (7+x)*x.
We also know the area is 170. Substitute this value for A and solve.
none of those are right it is 4 because there is no x behind the 4.

subtract the 2 to find the difference:
279.48 - 250.55 = 28.93
divide difference by actual amount:
28.93 / 279.48 = 0.1035
rounded to the nearest tenth = 10.4%
