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!! :))
