A rectangular yard measures 42 ft By 72 ft Is murdered and surrounded by a fence inside a walk that is 4 feet wide goes All the way along the fence find the area of the walk Be sure to include the correct unit in the answer

The area of the walk is 440.

Step-by-step explanation:

We have , a rectangular yard measures 42 ft By 72 ft Is murdered and surrounded by a fence inside a walk that is 4 feet wide goes All the way along the fence. That means we have a rectangle with dimensions of 42 ft by 72 ft and another rectangle that is concentric with dimensions less than 4 ft by previous rectangle i.e. (42-4) ft by (72-4) ft , which is 38 ft by 68 ft.

Now, we know that area of rectangle  =

Area of bigger rectangle  =

⇒

⇒

Similarly, Area of enclosed rectangle  =

⇒

⇒

Now, the area of walk =

⇒ area of walk =

⇒ area of walk =

∴ The area of the walk is 440.
