Answer:

Step-by-step explanation:
Area of a triangle is given a half the product of base by the perpendicular height:

Given h=9cm, and b=2.9cm, the area is calculated as:

Hence, area of the triangle is 13.05 sq cm
Answer:
a). y = 4.5
b) Scale factor = 
Step-by-step explanation:
a). Since, polygon Q is the scaled copy of polygon P
Both the figures will be similar.
Therefore, their corresponding sides will be proportional.

If x = 6,

y = 
y = 4.5
b). Since, polygon Q is the scaled copy of polygon P,
Polygon Q will be the image of preimage polygon P.
Scale factor = 
= 
The equation in standard form is Y=2x-3
