Answer:
27 m² (blue fabric)
9 m² (brown fabric)
Step-by-step explanation:
Area of a triangle = 1/2*base *height
Area of 4 triangles = 4* 1/2*3*4.5 = 27 m² (blue fabric)
Area of a square = side² = 3² = 9 m² (brown fabric)
Answer:
The scale factor was used in the dilation is 3
Step-by-step explanation:
Dilation is a kind of transformation that changes the size of figures
Image of a figure by dilation and the figure are similar
If a triangle dilated by a scale factor k then its image is similar to it, and the constant ratio between their corresponding sides is equal to k
∵ Δ ABC is dilated to form Δ DEF
∴ Δs ABC and DEF are similar
- That mean their corresponding sides have constant ratio
equal the scale factor of dilation
∴ 
Size of Δ DEF is greater than size of Δ ABC, that means k > 1
∵ AC = 2 units
∵ DF = 6 units
∵ 
∴ 
∴ 3 = k
∵ The scale factor of dilation is equal to the constant ratio k
∵ k = 3
∴ The scale factor was used in the dilation is 3
Answer:
12 inches ^2
Step-by-step explanation:
The area of a triangle is found by
A = 1/2 bh
A = 1/2 (6)*4
A = 12 inches ^2
