We could use Euler's polyhedron formula:
Answer:
6983/1000 OR 6.983
Step-by-step explanation:
6*1=6
9*1/10=9/10
8*1/100=8/100
3*1/1000=3/1000
6+9/10+8/100+3/1000=6983/1000
OR
6.983
You use feet to measure the length of a wall
The answer would be (18+45m) because you have to multiply the 9 to the 2 which equals 18 and then do the same for the 5m and which would be 45 because you add the variable at the end
