Answer:
Perimeter of MNO = 38.71 in.
Area of MNO = 63.73 sq. in.
Step-by-step explanation:
Since the two triangles are similar, this means that
- linear dimensions are proportional to ratio of corresponding sides
- areas are proportional to ratio of corresponding sides.
Ratio of corresponding sides of MNO to DEF
= 6.7/9
Therefore
Perimeter of MNO = P*6.7/9 = 38.71 in.
Area of MNO = A*(6.7/9)^2 = 63.73 sq. in.
all results have been calculated to the second place of decimal
