Answer:
Step-by-step explanation:
Since each fret marker is in the shape of a parallelogram, we would determine the area of each of the bottom fret markers by applying the formula for determining the area of a parallelogram. It us expressed as
Area = base × height
Each of the three bottom fret markers has a base that measures 52.5mm and a height of 6mm. Therefore, area of each the bottom fret markers is
52.5 × 6 = 315

Step-by-step explanation:
Given: In ΔMNO and ΔQRS

To prove that the triangles are similar by the SSS similarity theorem [corresponding sides of similar triangles are proportional], there must be the third pair of corresponding sides,
That must be
and
such that
