Answer 36

Which equation would best help solve the following problem?



Holly has a rectangular garden that measures 12 m wide by 14 m long. She wants to increase the area to 255 m^2 by increasing the width and length by the same amount. What will be the dimensions of the new garden?


255 = (12 + x^2)(14)

255 = (12)(14)

255 = (12 – x)(14 – x)


255 = (12 + x)(14 + x)
