Question

Find the area of the figure below, formed from a triangle and a rectangle, in square millimeters.

A figure is formed from a right triangle and a rectangle. The rectangle is 25 millimeters long and 2 millimeters wide. The legs that make up the right angle of the triangle are 15 millimeters and 20 millimeters. A. 350 square millimeters B. 200 square millimeters C. 175 square millimeters or D. 325 square millimeters

Answer 1

Answer:

B. 200 mm²

Step-by-step explanation:

The area of a rectangle part of the figure is found using length x width, which in this case is 25 x 2 = 50 mm²

The area of a triangle is found using $\frac{base*height}{2}$. Since the values given are the legs that make up the right angle, your base and height are 15 mm and 20 mm. This means the area is $\frac{15*20}{2}$, which is 150 mm².

The area of the figure as is whole is 50 + 150, which is 200 mm².
