Please help i have no clue what to do

b=3

Step-by-step explanation:

Pythagorean theorem

a²+b²=c²

use simple algebra to get the equation to say

a²-c²=-b² by subtracting b² on both sides and c² on both sides

plug in you numbers

4²-5²=b²

do the math

16-25=-9

square root it

b=√-9

b=3

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
