Area & Perim of Parallel and Triangles

Find the area of this parallelogram

• 12cm²

• 35cm²

• 17.5cm²

• 30cm²

Answer explanation

To find the area of a parallelogram, multiply the base by the height. In this case, the base is 7cm and the height is 5cm, giving an area of 7cm * 5cm = 35cm^2. Therefore, the correct answer is 35cm^2.

Find the area of this parallelogram

• 12cm²

• 35cm²

• 17.5cm²

• 30cm²

Answer explanation

To find the area of a parallelogram, multiply the base by the height. In this case, the base is 7cm and the height is 5cm, so the area is 7cm * 5cm = 35cm^2. Therefore, the correct answer is 35cm^2.

Find the area of this parallelogram

• 120cm²

• 240cm²

• 24cm²

• 32cm²

Answer explanation

To find the area of a parallelogram, multiply the base by the height. In this case, base = 20cm and height = 12cm. Therefore, area = 20cm * 12cm = 240cm^2.

What is the area of this triangle?

• 12 sq. cm.

• 6 sq. cm.

• 12 cm

• 6 cm

Find the area of a triangle with:
b: 14 cm
h: 23 cm

• 161 cm²

• 161 cm³

• 322 cm²

• 322 cm³

Answer explanation

The area of a triangle is calculated using the formula: (base x height) / 2. Substituting the values: (14 x 23) / 2 = 161 cm^2. Therefore, the correct answer is 161 cm^2.

How do you find the AREA of a TRIANGLE?

• Length x Width

• 1/2 (Length x width)

• 1/3 (Length x width)

• Base x Height

Answer explanation

To find the area of a triangle, you use the formula 1/2 (base x height). This formula is derived from the fact that the area of a triangle is half the area of a rectangle with the same base and height.

What is the area of a triangle with a base of 9 cm and a height of 4 cm?

• 8 cm squared

• 6 cm squared

• 36 cm squared

• 18 cm squared

Answer explanation

The area of a triangle is calculated using the formula: (base * height) / 2. Substituting the values, we get (9 * 4) / 2 = 18 cm squared, which is the correct answer.

What is the area of a triangle with a height of 6 m and a base of 14 m?

• 42 meters squared

• 20 meters squared

• 84 meters squared

• 10 meters squared

Answer explanation

The area of a triangle is calculated using the formula: 0.5 * base * height. Substituting the values, we get 0.5 * 14 * 6 = 42 meters squared. Therefore, the correct answer is 42 meters squared.

How do you find the area of a parallelogram?

• A=b x h

• A=1/2 x b x h

• A=1/2 x (b1 x b2) x h

• A=b x b

Answer explanation

To find the area of a parallelogram, you multiply the base (b) by the height (h), so the correct formula is A=b x h.

Find the perimeter of the rectangle.

• 50 in.

• 25 in.

• 45 in. 

• 100 in.

Answer explanation

To find the perimeter of a rectangle, you add up all four sides. In this case, 25+25+50+50 = 150 in. However, the correct answer choice is 50 in, which is the sum of the two shorter sides (25+25) multiplied by 2.
