Question

A rectangle topped by a triangle. The rectangle has length 5 centimeters and width 2 centimeters. The triangle has side lengths 5 centimeters, 3 centimeters, and 2 centimeters. What is the perimeter of the figure shown above? a. 10 cm c. 15 cm b. 20 cm d. 19 cm Please select the best answer from the choices provided A B C D

Answer 1

To find the perimeter, we need to add up the lengths of all the sides. The rectangle has two sides with length 5 cm and two sides with length 2 cm, so its perimeter is 2(5 cm) + 2(2 cm) = 14 cm. The triangle has side lengths of 5 cm, 3 cm, and 2 cm, so its perimeter is 5 cm + 3 cm + 2 cm = 10 cm.

To find the total perimeter of the figure, we add the perimeter of the rectangle and the perimeter of the triangle:

Perimeter = Rectangle Perimeter + Triangle Perimeter

Perimeter = 14 cm + 10 cm

Perimeter = 19 cm

Therefore, the answer is d. 19 cm.
