Hi,everyone. I have a advanced maths exercise I can't solve. The question is about constructing a sheep pen:
A farmer wishes to build a rectangular sheep pen with a 160m fence,using one side of the existing shed as the side. The shed is also rectangular of measurement 20m X 20m.
a.) Find the measurement and the area of the sheep pen if one side of the existing shed is used as the width of the sheep pen.
b.) By using the fence of the same length and using the width of the shed as the part of the width of the sheep pen,find the length and width of the sheep pen with "maximum area".
***Please help me to solve the two questions. I would like you to check my answer for (a) ques: width of the sheep pen: 20m, its length 70m(only one width of sheep pen is subtracted since no fence will be constructed at the width of the shed) and the area is1400m square.
For ques,(b) chapter differentiation is related . Pls tell me clues and the answers so that I can discover. Thanks!
