One side (l) = 2x-1
other side (w) = 3x

perimiter = all of the sides added together

perimiter = 2l + 2w

perimiter = 2(2x-1) + 2(3x)

2(2x) - 2(1) + 2(3x) = 4x - 2 + 6x

perimiter = 10x - 2

<em>The previous statement is incorrect because the student did not distribute the 2 onto the -1.</em>

Answer:

Step-by-step explanation:

Your question has typographical errors. The equation is 2a + b = 15.7, not 2e+b-15.7

2a + b = 15.7

b = 15.7  - 2a

since a > b, a = 6.3 cm

b = 15.7 - 2·6.3 = 3.1 cm
