    its 7.5 and you only need to find the base and height to find the area which is 7.5 right?

    7.5 correct now, to get the rectangle, multiply by 2

    now we know area of a rectangle is base times height, so we have the base which is 5 and we know the area is 15 so we can make the equation 15 = 5x (what times 5 = 15)

    so 3 would be the length for the missing side of the rectangle! Great work!
