Answer:
Step-by-step explanation:
perimeter of a rectangle=P = 2l + 2w
formula for area-
rectangle= l x w
square= a^2
triangle=1/2 b×h
circle= πr^2
Trapezoid=1/2 (a + b)h
Ellipse=πab
0.4 times 3 = 1.2

Answer:
b
Step-by-step explanation:
Using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (4, 1)
d =
=
= = → b
