Question

The perimeter of a rectangle is 100 cm which of the following functions express the area of the rectangle in terms of the width x?

Answer 1

Answer :please mark me as the brainliest

Step-by-step explanation:

the perimeter of a rectangle is 100cm, and its diagonal has length x. express the area of the rectangle as a function of x.

-----

Perimeter = 2(length + width) = 100 cm

length + width = 50 cm

---

L^2 + W^2 = x^2

---

 

length = sqrt[x^2-width^2]

width = sqrt[x^2-length^2]

----------

Area = length*width = sqrt[(x^2-W^2)(x^2-L^2)]
