Answer 2

Step-by-step explanation:

1. Perimeter = 20 cm

Let each side of the square be x cm.

So,

B.T.P

x+x+x+x = 20

=> 4x = 20

=> x = 5

So , each side of square = 5 cm

Area = Side² = 5² = 25 cm² [ Ans ]

2. Area of the wall = 3*5 = 15m ²

Area of gate = 2*1 = 2m²

Remaining area of wall = 15-2 = 13m²

Cost = 13 * 100 = Rs. 1300 [ Ans ]
