Help with the perpendicular lines please

Red and Green are parallel

Black and Blue are perpendicular

Step-by-step explanation:

Parallel lines need to have the same slope. Lines red and green both have a slope of 1/2.

The slopes of two lines that are perpendicular have to be opposite reciprocals, and must be multiplied together to get -1. Line black has a slope of -4, and line blue has a slope of 1/4. Both of them multiplied together equals -1.

step-by-step explanation:

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.'
