Manny wants to sew a ribbon border around a small triangular cushion with sides of square root 45cm, 6 square root 5cm and square root 125cm.
A) determine the exact length of ribbon Manny needs.
B) determine the!approximate length Manny needs to one decimal point
sqrt%28+45%29%2B+6+sqrt%285%29+sqrt+%28125%29 = total length
3%2Asqrt%285%29%2B+6+sqrt%285%29%2B5+sqrt+%285%29 =13sqrt%285%29
= =13sqrt%285%29

=13sqrt%285%29= 13*2.236
=29.1 cm
