Question

The area of a rectangle is given by (x2 + 5x - 35) sq. units. Find the length and breadth of the rectangle​

Answer 1

Answer:

l = x+7 and b = x-5

Step-by-step explanation:

given, the area of a rectangle = x² + 2x - 35 (check your question)

                                                 = x² + 7x -5x - 35

                                                 = x(x+7) -5(x+7)

                                                 = (x+7)(x-5)

ie, l*b = (x+7)(x-5)

so, l = x+7 and b = x-5
