A tile is shaped like the trapezoid shown. The short base is 18 cm and the long base is 30 cm. What is the area of the tile in square centimeters?

• 72 cm²

• 50 cm²

• 42 cm²

• 80 cm²

Answer explanation

The area of a trapezoid is calculated by (1/2) * (sum of parallel sides) * (height). In this case, (1/2) * (10 + 14) * 5 = 50 cm², so the correct answer is 50 cm².

The diagram below shows a window shaped like a trapezoid. What is the area of the window in square meters?

• 4.6 m²

• 6.9 m²

• 5.5 m²

• 5 m²

Answer explanation

The area of a trapezoid is calculated by averaging the lengths of the parallel sides and multiplying by the height. In this case, the area is (3+8)/2 * 2 = 5.5 m², so the correct answer is 5.5 m².

The height of a trapezoid is 12 inches. The bases of the trapezoid measure 18 inches and 23 inches. What is the area of the trapezoid in square inches?

• 414 in.²

• 246 in.²

• 216 in.²

• 492 in.²

Answer explanation

To find the area of a trapezoid, use the formula: Area = (1/2) * (sum of bases) * height. Plugging in the values, we get: Area = (1/2) * (18 + 23) * 12 = 246 in.^2. Therefore, the correct answer is 246 in.^2.

A box is shaped like a rectangular prism. The box is 15 inches long, 4 inches wide, and 12 inches tall. What is the volume of the box in cubic inches?

• 72 in.³

• 31 in.³

• 310 in.³

• 720 in.³

Answer explanation

To find the volume of a rectangular prism, multiply the length, width, and height. In this case, 15 x 4 x 12 = 720 in.^3. Therefore, the correct answer is 720 in.^3.
