Answer:
The length of the mural was 90 inches.
Step-by-step explanation:
Brianna went on a trip to the art museum and sketched a scale drawing of a rectangular wall mural.
She used a scale factor of 0.2 = [tex]\frac{1}{5}[/tex]
the sketch was 18 inches long.
Let the length of the mural be x
the actual length of the mural = [tex]\frac{1}{5}[/tex]x = 18
x = 18 × 5
x = 90
The length of the mural was 90 inches.
