Question

can you please explain
a) Perimetre=30 cm , unequal side= 8 cm​

Answer 1

Answer:

If we take the equal sides as x

Then length of unequal side=8 cm

And sum of all sides I.e. perimeter =30

So,if we calculate

x+x+8=30

2x+8=30

2x=30-8

2x=22

x=11

Hence,the length of each equal side is 11cm

Hope this will help you
