**Answer:**

**option (b) is correct. **

**The dimensions of the original rectangle could be 4 × 5 yards**

**Step-by-step explanation:**

Given : A rectangle is dilated by a factor of the area of the new rectangle is 4 square yards .

We have to find the dimensions of the original rectangle.

**Dilation is a property to resize the figures without changing measures of angles. It just reduce the given figure if dilation factor is less than 1 and enlarge if dilation factor is greater than 1.**

Since, given **dilation **factor is , which is less than 1. Thus, the the resultant figure is smaller in size then the original

**Original × dilation factor = new **

**Here, given figure is rectangle so, **

**Original rectangle × dilation factor = new rectangle**

Given :

new rectangle = 4 square yards

**dilation **factor =

Original rectangle × = 4 square yards

Original rectangle = 4 × 5 square yards

**Original rectangle = 20 square yards**

**Thus, option (b) is correct. **

**Thus, the dimensions of the original rectangle could be 4 × 5 yards**
