Solve the following problems.
1) Perimeter of a square is 20 cm, then what will be the area of that square.
2) A gate having dimensions 2 m X 1 m is in the wall of 3 m X 5 m. If the cost of colouring is Rs. 100 per m2 , find the total cost of colouring the wall.​

Answer 1

Answer:

1) 25

2) 1300

Step-by-step explanation:

2) Area of gate = 2m * 1 m = 2 m^2

Area of wall = 5m * 3m = 15 m^2

Total area of wall = 15 - 2 m

13 m^2

cost of colouring = 13 * 100

1300 rupees
