The canvas of a painting has an area of 64 ft2. What length of frame is needed for the border of the painting?

8

Step-by-step explanation:

Assuming, the canvas has the shape of a square. By the square area formula we can derive its side:

Then Each side of the painting measures 8 feet, the length of frame must have 8 feet long, and the width is decided by the framer.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
