A rectangular front-wall of a hospital has a perimeter equals to 294 meters. If it's length is 85 meter find its area?

5270 m²

5310 m²

None of these

Given:

Perimeter = 294 m

Length = 85 m

Let's denote the width as W. The formula for the perimeter of a rectangle is:

Perimeter = 2(Length + Width)

294 = 2(85 + W)

147 = 85 + W

W = 62 m

Now, to find the area:

Area = Length * Width

= 85 * 62

= 5270 m²
