The width and length of a rectangle are given by two consecutive integers. Write an expression for the area of the rectangle. Use x for the variable.

The product of two consecutive integers is 30. Find the two integers.

The smaller of the two integers is , and the larger of the two is .

Area of rectangle = length x width = lw

Area of rectangle = 30 = x * (x + 1)

30 = x^2 + x + 0
0 = x^2 + x - 30
(x - 5)(x + 6)
x = (5, -6)

Smaller of two integers is -6
Larger of two integers is 5
