4. Ellen wants to put an underground sprinkler system in her backyard. Her backyard measures 62 ft across and 78 ft wide. How long would the underground sprinkler system have to be? photo attatched has photo of pipe- please dont send link for answer​

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

final total: 63
