A campaign manager is creating campaign signs that advertise his political candidate. The campaign manager would like to maximize the surface area of the signs so that passersby have the greatest chance of seeing them. In keeping with local campaign laws, the campaign signs must have a perimeter of 160 inches. Explain how the campaign manger can find the width and height of the signs that maximize area. Round your values to the nearest tenth of a square inch.

Will mark brainliest please help!!

Respuesta :

So if length be L and width be B

We know

Perimeter

  • 2(L+B)

So if he wants to create a rectangle advertisement

  • 2(L+B)=160
  • L+B=80

The sum of length and breadth must be 80

If it's square

  • 4S=160
  • S=40in

It should have side as 40in
