Question

Last one guys i promise ........the area of a rectangle is 112. The length is 7, and the width is √x. What is the value of x? What is the width of the rectangle? (Hint: The area of a rectangle is equal to length times width.)

Answer 1

use the hint

Answer 2

area = length * width
112 = 7 * \(\sqrt{x}\)

Answer 3

divide both sides by 7

Answer 4

112/7 = \(\sqrt{x}\)

16 = \(\sqrt{x}\)

\(16^2 = x\)

\(x = ? \)

Answer 5

uhh, 5 ?
