Answer: Option A

Explanation:

To find the area of the garden, excluding the walkway, you can subtract the area of the walkway from the total area of the garden.

The garden's total length is 100 meters, and it has a walkway of 2 meters on each side. So, the effective length of the garden is 100 meters - 2 meters (on one side) - 2 meters (on the other side) = 96 meters.

Similarly, the garden's total width is 60 meters, and it has a walkway of 2 meters on each side. So, the effective width of the garden is 60 meters - 2 meters (on one side) - 2 meters (on the other side) = 56 meters.

Now, calculate the area of the garden:

Area = Length × Width Area = 96 meters × 56 meters Area = 5376 square meters

So, the area of the garden, excluding the walkway, is 5376 square meters. The correct answer is 5376.

A. 700
B. 650

Area without path = 50 x 10 = 500 sq. m.

Area of the path = 1200 - 500 = 700 sq. m.
