the area of a concrete rectangular pathway is 350 m squared and its perimeter pathway is 90m. What is the length of the pathway?

Sagot :

Perimeter = 2(l + w) = 90
2(l + w) = 90
l + w =45

Area = lw = 350

We look for two numbers with a product of 350 and a sum of 45.
2 + 175 = 177 X
5 + 70 = 75 X
7 + 50 = 57 X
10 + 35 = 45 √

Therefore the length off the pathway is 35m.
