Question

A rectangular lot 50 feet by 100 feet is surrounded on all sides by a concrete walk 5 feet wide. Find the number of square feet in the surface of the walk.

Answer 1

The area of the surrounding are can be found by the following method-

Answer 2

Answer:

$1600 ft^2$

Step-by-step explanation:

Length of rectangular plot = 50 feet

Breadth of rectangular plot = 100 feet

we are given that rectangular Plot is surrounded on all sides by a concrete walk 5 feet wide.

Outer length = 50+(5+5)=60 feet

Outer Breadth = 100+(5+5) =110 feet

Area of path = Outer area - Inner area

                     = $(110 \times 60)-(100 \times 50)$

                     = $1600 ft^2$

Hence the area of the path is  $1600 ft^2$
