Answer:
b
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (3, 4 )
m = =
y = x → b
The area of a parallelogram is A=bh
By isolating b, we can find the value
A=bh
b=
b=
b= 6 ft
The base is 6 ft long
By isolating b, we can find the value
A=bh
b=
