Question 790963: write an equation and solve for x if area of a rectangle is 70sq units and the length is x+4 and width is 7 Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Area of rectangle = length * width
70 = (x + 4) * 7
70 = 7x + 28
7x = 70 - 28
7x = 42
x = 6
Length = 10 units.
Hope this helps.
