Answer:
Step-by-step explanation:
Given
See attachment for table
Required
Determine
From the table;
when
So:
What about it.....????
81000 or 8.1
1m = 100cm
10m = 1000cm
a= b*h
a= 1000cm * 810cm
= 810000
1 = 10000
810000 = 8.1
15.9778
≈ 16
Formula= a² + b² = c²
7.7² + 14² = 255.29
√255.29 = 15.9778 or ≈16
