Please help me .....

Answer:

150 feet of flowers would be planted along side C

$a=5400$

Step-by-step explanation:

Use the pythagorean theorem to find the length of side C

$a^2+b^2=c^2$

Input the corresponding numbers into the formula

$90^2+120^2=c^2$

$c^2=22500$

$c = \sqrt{22500} \\ c=150$

150 feet of flowers would be planted along side C

To find the area multiply the base and height together, and divide the total by two

$a = \frac{bh}{2}$

$a = \frac{90 * 120}{2} \\ a=5400$

jenyasd209 [6]

Answer:

This is a 12.9% change - increase

Step-by-step explanation:

To find the percent change, use the percent change equation.

(New - Old)/(Old) * 100 = Percent Change

(525 - 465)/(465)*100 = Percent Change

60/465 * 100 = Percent Change

.129 * 100 = Percent Change

12.9% = Percent Change
