Question

The perimeter of the rectangle below is 174 units. Find the length of side BC. Write your answer without variables.

Answer 1

BC= 39



Explanation:


4z+4z+3z+3+3z+3=174

8z+6z+6=174

14z+6=174

Subtract 6 from both sides

14z=168

Z=12


So then 3*12+3=39


And you can check by doing 39+39+48+48
And it equals 174
