Answer 1

Answer:

Step-by-step explanation:

First we will find the area

Given - length = 60m 50cm = 60.5m

Breadth = 39. 5m

Area of rectangle = l x b

= 60.5 x 39.5

= 2389. 75

= 23.89sq.m

Cost of 1 per Sq. m = 2.20

Area = 23.89sq.m

Cost= 2.20 x 23.89

= 52. 55

Therefore approx is 53sq.m

She should take 19 rounds.
