Question

a rectangular computer screen has an area o A square inches. The width of the computer is 7 inches. Which equation rpresents x the length of the computer screen in inches

Answer 1

x = A/7

Explanation:

Given that the screen is rectangular, recall that the area A of a rectangle whose length is L and width is W is given as

A = L * W

Hence if the width is 7 inches and the length is x inches then the area which is A square inches is connected to both sides as

A = x * 7

Divide both sides by 7

x = A/7 inches
