Answer : The area the fence encloses is, 120 ft²
Step-by-step explanation :
As we are given that Penelope built a fence that is 10 feet by 12 feet which will resemble the shape of rectangle.
As we know that:
Area of rectangle = Length × Breadth
Given:
Length = 12 feet
Breadth = 10 feet
Now put all the values in the above formula, we get the area of fence encloses.
Area of rectangle = Length × Breadth
Area of rectangle = 12 feet × 10 feet
Area of rectangle = 120 feet² = 120 ft²
Therefore, the area the fence encloses is, 120 ft²
