Answer:
320 meters
Step-by-step explanation:
x² + 200x = 166400
It's a square, area should be side²
x² + 2(x)(100) = 166400
x² + 2(x)(100) + 100² = 166400 + 100²
(x + 100)² = 176400
x + 100 = 420
Since these are sides, we just consider the positive square root
x + 100 = 420
x = 320m
U have to cross out the 10 then u have those 4 5s 5x5=25 5x5=25 25+25=50.
