Effectus [21]

The letter i in mathematics represents √-1. So, keep in mind. i = √-1.

Let's factor √-32 with the i in mind.

√-32 = √(32 * -1) = √32 * √-1 = √32i.

Identify the area of the trapezoid. Please help!

Evgen [1.6K]

Answer:

$\large\boxed{A=46x\ m^2}$

Step-by-step explanation:

The formula of an area of a trapezoid:

$A=\dfrac{b_1+b_2}{2}\cdot h$

b₁, b₂ - bases

h - height

We have

b₁ = 12m , b₂ = 6.4 m, h = 5x m.

Substitute:

$A=\dfrac{12+6.4}{2}\cdot5x=\dfrac{18.4}{2}\cdot5x=9.2\cdot5x=46x$
