The area of the concrete pathway is 350 m^2 and its perimeter pathway is 90 m. What is the length of the pathway?

Sagot :

A=350m²
P=90m

Let x-length and y-width
xy=350

(2x+2y=90)/2
x+y=45

Then find the factors of 350 that have the sum of 45.
xy=350 - (1&350 = 351) (2&175 = 177) (5&70 = 75) (7&50 = 57) (10&35 = 45)

Then x(length) and y(width) could be 35m and 10m :)
