If a storm window has an area of 400 square inches, what are the dimensions if the window is 12 inches higher than it is wide ( wxh ) ?

Area of the window= 400 square inches
Let the width of the window be 'x' inches,
then the height of the window will be 12 times 'x' inches.

We know, Area of the window= width X height
therefore, 400= x inches X 12x inches
              =>400=12 inches
              =>=400/12 inches
              =>x=5.77 inches
Therefore, width=5.77 inches and height=12X5.77=69.28 inches

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
