The area of a photograph is 15 square inches. If the width of the photograph is 3 inches, what is its length?
JUST TELL US THE ANSWER!!
AND MAKE IT TRUE
A = L * W
15 = 3L
15/3 = L
5 = L
What is the answer to the question?
To find the length of the photograph, we can use the formula for the area of a rectangle: Area = length × width.
Given that the area of the photograph is 15 square inches and the width is 3 inches, we can substitute these values into the formula to solve for the length.
15 square inches = length × 3 inches
To isolate the length, we'll divide both sides of the equation by 3 inches:
15 square inches ÷ 3 inches = length
Simplifying the equation:
5 inches = length
Therefore, the length of the photograph is 5 inches.
