Example Question #281 : Geometry

Find the area of the trapezoid.

3

Possible Answers:

\(\displaystyle 408\)

\(\displaystyle 391\)

\(\displaystyle 400\)

\(\displaystyle 396\)

Correct answer:

\(\displaystyle 400\)

Explanation:

Recall the formula for finding the area of a trapezoid:

\(\displaystyle \text{Area}=\frac{base_1+base_2}{2}\times(height)\)

Now, plug in the values for the bases and the height to find the area.

\(\displaystyle \text{Area}=\frac{14+26}{2}\times(20)=400\)

Example Question #282 : Geometry

Find the area of the trapezoid.

Possible Answers:

\(\displaystyle 209\)

\(\displaystyle 221\)

\(\displaystyle 442\)

\(\displaystyle 341\)

Correct answer:

\(\displaystyle 221\)

Explanation:

Recall the formula for finding the area of a trapezoid:

\(\displaystyle \text{Area}=\frac{base_1+base_2}{2}\times(height)\)

Now, plug in the values for the bases and the height to find the area.

\(\displaystyle \text{Area}=\frac{1+25}{2}\times(17)=221\)

Example Question #283 : Geometry

Find the area of the trapezoid.

Find the area of the trapezoid.

7

Possible Answers:

\(\displaystyle 200\)

\(\displaystyle 316\)

\(\displaystyle 208\)

\(\displaystyle 214\)

Correct answer:

\(\displaystyle 208\)

Explanation:

Recall the formula for finding the area of a trapezoid:

\(\displaystyle \text{Area}=\frac{base_1+base_2}{2}\times(height)\)

Now, plug in the values for the bases and the height to find the area.

\(\displaystyle \text{Area}=\frac{6+20}{2}\times(16)=208\)
