​

Answer 1

Answer:

5.16m

Step-by-step explanation:

length of the chart paper = 15m 20cm

(when concerted in m...) = 15.2m

breadth of the chart paper = 8m 30cm

= 8.3m

area of chart paper = lxb

= 15.2×8.3

= 126.16

area of 1 square poster = side × side

= 5m 50cm×5m 50cm

= 5.5×5.5

= 30.25

area of 4 square poster = 30.25 × 4 = 121

left over chart paper = 126.16 - 121

= 5.16m

or 5m 16 cm

hope it helps!! :))
