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. the sketch was 12 inches wide and 18 inches long. what was the length of the mural? 3.6 inches 18.2 inches 60 inches 90 inches

we are given dimensions of the sketch :

length = 12 inches.

width = 18 inches.

given scale factor = 0.2.

the actual dimensions of the mural would be: the sketch dimensions divide by scale factor.

(because the mural would be larger than the sketch dimensions).

we need to find the actualy length of the mural.

therefore,

the length of the mural = 12 inches ÷ 0.2 = 60 inches.

$450 i think. hope this ☺
