What is the area of this trapezoid?

liberstina [14]

Answer:

$7.5\:\text{square units}$

Step-by-step explanation:

The area of a trapezoid is given by the average of the bases multiplied by the height.

What we're given:

Height of 3
Bases of 1 and 4

The average of the bases 1 and 4 is equal to $\frac{4+1}{2}=\frac{5}{2}=2.5$

Therefore, the area of the trapezoid is $2.5\cdot 3=\boxed{7.5\:\text{square units}}$

<span>Simplifying X2 + -4 = 0 Reorder the terms: -4 + X2 = 0 Solving -4 + X2 = 0 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + X2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + X2 = 0 + 4 X2 = 0 + 4 Combine like terms: 0 + 4 = 4 X2 = 4 Simplifying X2 = 4 Take the square root of each side: X = {-2, 2}</span>
