Answer:

Breadth = 25 m

Step-by-step explanation:

Cost per sq.m = Rs 22

Total cost = Rs 4400

Total sq.m = 4400÷22 = 200

Therefore, 200 = Area

L = 8m

B = A÷L

= 200÷8

= 25 m

Answer 2

Answer:

The Length of the room = 25 m

Step-by-step explanation:

Rate of Painting the room = Rs 22

Cost of painting the room = Rs 4400

COST = RATE * AREA

4400 = 22 * A

4400/22 = A

Area of the room = 200 m^2

Breadth of the room = 8 m

AREA = LENGTH * BREADTH

200 = l * 8

200/8 = l

Length of the room = 25 m
