Answer:
Step-by-step explanation: 1m = 100cm
Given - perimeter of floor = 30cm. (square)
Measure of one side of floor
Area of square = 4 x sides
30 = 4 x sides
Side= 30 / 4
= 7.5 cm (Breadth)
Area of wall (rectangle)
Area of rectangle = l x b
= 300 x 7.5
= 2250
Therefore area of one wall is 2250sq.cm
Area of 4 walls
= 4 x 2250
= 9000sq.cm
