Question

A triangle has side lengths of (3.76 + 1.7) centimeters, (1.36 + 1.1) centimeters,
and (7.1c +5.1) centimeters. Which expression represents the perimeter, in
centimeters, of the triangle?

Answer 1

Answer:

Step-by-step explanation:

our triangle has one length:     3.76+1.7=5.46

                           another side: 1.36+1.1=2.46

                            last side:        7.1+5.1=12.20

Perimeter is=5.46+2.46+12.20=20.12 cm
