If you don’t know the answer pls don’t reply thank you
nikdorinn [45]

Answer:

Is B

Step-by-step explanation:

It's B because you use cups with the tablespoons to find the answer. 2 is cups, and it's on the numerator, and 1.5 is cups. It would have to be a numerator since you would only use denominators to plug in the value of tablespoons in the equation. <em>v </em>would be the denominator with 1.5 as the numerator since we are trying to find v with 1.5, so 1.5 has to be in the same fraction.

Hope this helps!

Helps plz,

Here's the solution,

there's a rectangle with sides 4x and 2x

So, area of rectangle :

=》4x × 2x

=》8x²

now, let's divide the kite into two equal triangles with base = 4x

and height = x

area of each triangle :

=》

\dfrac{1}{2}  \times base \times height

=》

\dfrac{1}{2}   \times 4x \times x

=》

2x \times x

=》

2{x}^{2}

now, area of each triangle = 2x²

and there are two triangles so,

Area of the kite will be :

=》2 × 2x²

=》4x²

Area of shaded region =

=》Area of rectangle - Area of kite

=》8x² - 4x² = 4x²

hence, correct option is B.
