1. A farmer wants to build a fence around a rectangular area of his farm with one side of the region against his barn. He has 76

Arte-miy333 [17]

Answer:

19 ft by 38 feets

Step-by-step explanation:

Given that :

Available fencing = 76 feets

Rectangular fencing with 3 sides

Let the 3 sides be :

x, x, y

x + x + y = 2x + y = 76

y = 76 - 2x

Area = x * y = xy

Area = (76 - 2x) * x

Area = 76x - 2x²

Take derivative of Area with respect to x ; dA

dA /dx = 76 - 4x = 0

76 - 4x = 0

-4x = - 76

x = 76 / 4

x = 19

2x + y = 76

2(19) + y = 76

38 + y = 76

y = 76 - 38

y = 38

Hence, dimension : 19feet by 38 feets
