Let
x--------> the number

we know that
11²=121
12²=144

then
x² must be greater than 121 and less than 144

case a) √115
if x=√115
then
x²=115-------> is not greater than 121

case b) √121
if x=√121
then
x²=121-------> is not greater than 121

case c) √136
if x=√136
then
x²=136-------> is greater than 121 and is less than 144------> is ok

case d) √150
if x=√150
then
x²=150------> is not less than 144

therefore

the answer is
√136

Hello,

Let's solve this problem mathematically.

For first design...

$f = 200 \times 15 = 3000$

For second design...

$s = 200 \times 55 = 11000$

To use an entire budget for design she must order.

For first design

5800÷3000 = 1.93f

or
For second design

5800÷11000=0.52s

Hope this helps answer your question!
