Answer:
d = 9
Step-by-step explanation:
Calculate the slope of ab then equate to 3.
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (4, 6) and (x₂, y₂ ) = (d, 21)
m =
=
= 3 ( multiply both sides by d - 4 )
3(d - 4) = 15 ( divide both sides by 3 )
d - 4 = 5 ( add 4 to both sides )
d = 9
Answer:
Blue fabric (triangles) = 27 m²
Green fabric (square) = 9 m²
Step-by-step explanation:
✔️Blue fabric (triangles) = 4(area of triangular face)
= 4(½*b*h)
b = 3 m
h = 4.5 m
= 4(½*3*4.5)
= 27 m²
✔️Green fabric (square) = area of the square base
= s²
s = 3
Area = 3²
= 9 m²
