Use the image to answer the question.
An illustration shows a trapezoid with top side as 4 centimeters, and the left as the longest side of 9 centimeters. The opposite parallel side on the right is 6 centimeters. A diagonal bottom side is 5 centimeters. The top side is perpendicular to the left and right sides as denoted by right two angle symbols. A perpendicular dotted line from the bottom right vertex to the left side is drawn. The dotted line makes one right angle symbol with right side and two right angle symbols with the left side. It forms a right triangle at the bottom of the trapezoid, with the 5 centimeter side as the hypotenuse.

To find the area of a trapezoid, you can use the formula: Area = 1/2 * (a + b) * h, where a and b are the lengths of the parallel sides and h is the height (distance between the parallel sides).
First, find the height of the trapezoid using the Pythagorean theorem in the right triangle formed at the bottom:
c^2 = a^2 + b^2
5^2 = 4^2 + h^2
25 = 16 + h^2
h^2 = 9
h = 3 cm
Now, plug in the values into the area formula:
Area = 1/2 * (6 + 4) * 3
Area = 1/2 * 10 * 3
Area = 5 * 3
Area = 15 cm squared
Therefore, the area of the quadrilateral is 15 cm squared.
The formula for the area of a trapezoid is: A = 1/2 * (a + b) * h, where a and b are the lengths of the parallel sides, and h is the height.
Given:
Top side = 4 cm (a)
Longest left side = 9 cm (b)
Right side = 6 cm
Diagonal bottom side = 5 cm (h)
First, we need to find the height (h) using the Pythagorean theorem:
h = √(5^2 - (9 - 6)^2)
h = √(25 - 3^2)
h = √(25 - 9)
h = √16
h = 4 cm
Now we can calculate the area:
A = 1/2 * (4 + 6) * 4
A = 1/2 * 10 * 4
A = 5 * 4
A = 20 cm^2
Therefore, the area of the quadrilateral is 20 cm^2.
Given:
Top side (a) = 4 cm
Longest side (b) = 9 cm
Right side = 6 cm
Diagonal (height) = 5 cm (h)
The height of the trapezoid can be calculated using the Pythagorean theorem in the right triangle formed at the bottom:
h^2 = 5^2 - (9 - 6)^2
h^2 = 25 - 9
h^2 = 16
h = 4 cm
Now we can calculate the area using the formula for the area of a trapezoid:
A = 1/2 * (a + b) * h
A = 1/2 * (4 + 9) * 4
A = 1/2 * 13 * 4
A = 6.5 * 4
A = 26 cm²
Therefore, the correct area of the trapezoid is 26 cm².
Given:
Top side (a) = 4 cm
Longest side (b) = 9 cm
Right side = 6 cm
Diagonal (height) = 5 cm (h)
First, we need to find the height (h) using the Pythagorean theorem in the right triangle formed at the bottom:
h^2 = 5^2 - (9 - 6)^2
h^2 = 25 - 3^2
h^2 = 25 - 9
h^2 = 16
h = 4 cm
Now we can calculate the area of the trapezoid using the formula:
A = 1/2 * (a + b) * h
A = 1/2 * (4 + 9) * 4
A = 1/2 * 13 * 4
A = 6.5 * 4
A = 26 cm²
Therefore, the correct area of the trapezoid is 26 cm².
