What is the area of the trapezoid? The diagram is not drawn to scale.

Katyanochek1 [597]

Answer:

The area of trapezoid is 72 cm²

Step-by-step explanation:

Given : A trapezoid with given dimensions.

We have to find the area of trapezoid ABCD.

Consider the given trapezoid ABCD ,

AB = EF = 8 cm

and CE = FD = 4 cm

Then CD = CE + EF + FD = 4 + 8 + 4 = 16 cm

Thus, Area of trapezoid = $\frac{1}{2}\cdot \text{(Sum of parallel sides)} \cdot height$

here, height = 6 cm

and sum of parallel sides = AB + CD = 16 + 8 = 24 cm

Thus, Area of trapezoid = $\frac{1}{2}\cdot 24 \cdot 6$

Simplify, we have,

Area of trapezoid = 72 cm²

Thus, The area of trapezoid is 72 cm²

5. As two boats are coming to the end of a race, a top view of their positions is

Dafna1 [17]

The distance of the boat on the right to the finish line is 297.29 m and the distance of the boat on the left to the finish is 294.11 m, so the boat on the left will reach the finish line faster.

<h3>How do you know which boat will reach the finish line faster? </h3>

The image shows two triangles of which we know an angle and the value of the opposite leg. Therefore, we can perform a mathematical operation to know the value of the hypotenuse of these triangles, which would be the distance of the boats to the goal as shown below.

h = hypotenuse

Right Boat

Sen 22° = $\frac{110 m}{h}$

h = $\frac{110 m}{ Sin 22}$

h = $\frac{110 m}{0.37}$

h = 297,29 m

Left boat

Sen 20° = $\frac{100}{h}$

h = $\frac{|00 m}{ Sin 20}$

h = $\frac{100 m}{0.34}$

h = 294,11 m

According to the above, the distance of the boat on the left is less, so it can be inferred that this boat will reach the finish line faster.
