Question

Please help:A rectangular flower bed is enlarged so that its area increases by 24 ft². The enlarged flower bed is a rectangle and its area is x^2 + 11x + 24 ft².Which expressions represent the dimensions of the flower bed before the increase?Enter your answers in the boxes. __ft by __ ft

Answer 1

Enlarged area = x^2 + 11x + 24 ft²

Original area =

a + 24 ft^2 = x^2 + 11x + 24 ft²

a = x^2 + 11x + 24 ft² - 24 ft^2

a = x^2 + 11x

Factored:

a = x (x + 11 )

Dimensions before the increase

x ft by (x-11) ft
