In front of a school are several gardens in rectangular raised beds. For the area of a rectangular garden .given, use factoring to find the possible dimensions. Could the garden be a perfect square? If so, explain why.

The correct answer is: x-10 and x-10 are possible dimensions of the garden. yes,the garden is a perfect square as length and breadth are equal.

Ans:- x - 10 and x - 10 are possible dimensions of the garden. yes, the garden is a perfect square as length and breadth are equal.
Given, 
Write
As 
Here a = x ; b = 10
We get
As the garden is rectangular , we can write area A =  length × breadth
The only possibility is length = x-10 and breadth = x-10
As length = breadth = x-10 the garden is a perfect square .
