10 rows with 10 chairs in each row is the best way to arrange 100 chairs to arrange for an assembly into equal rows.

A teacher has 100 chairs to arrange for an assembly into equal rows.

That is we have to find an array such that the chairs are equally distributed.

If we arrange 10 chairs in each row and form 10 such rows than the total of  100 chairs could be arranged.

Since 10×10=100.

Hence, from this arrangement we get that:

Number of rows=10

and number of chairs in each row=10

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
