Ответ:
So, the original dimensions are 8ft x 8ft. We want to increase the length by 3, so l = x + 3. And we want to decrease the width by 3, so w = x - 3. The expression would be lw = (x + 3)(x - 3). To solve for the new area, we would have this equation lw = 11 x 5 = 55. Therefore, the correct option is option B.
Hope this helps!! :)
