Answer:
The answer to your question is: width = 1.47 and length = 7.47 m
Step-by-step explanation:
Data
length = width + 6 cm = x + 6
width = x
Area = 11 cm²
11 = (x + 6)x Substitution
11 = x² + 6x Simplify
x² + 6x = 11 Factorise
x1 = 1.47 x2 = -7.47 length can not be negative
width = 1.47 cm
length = 1.47 + 6 = 7.47 m
