Answer:

The length of the mural was 90 inches.

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 =
(1)/(5)

the sketch was 18 inches long.

Let the length of the mural be x

the actual length of the mural =
(1)/(5)x = 18

x = 18 × 5

x = 90

The length of the mural was 90 inches.
