Answer 2

To construct the rectangle ABCD with sides AB = 4 cm and AD = 6 cm, we can follow these steps:

1. Draw a line segment AB with a length of 4 cm. 2. From point A, draw a line segment AD with a length of 6 cm, forming a right angle at A. 3. To find point M, where the ray AM intersects CD, we need to construct a 25-degree angle at point A. Here's how you can do it: - Set your compass to a convenient radius (e.g., 5 cm) and draw an arc intersecting AB at point X. - Without changing the compass radius, draw another arc intersecting the previous arc at point Y. - Draw a line segment AY. - Bisect the angle between AX and AY to find the 25-degree angle. Label the point of intersection with CD as M. 4. Connect points M and D to form the triangle MAD.

To find the area of triangle MAD, we can use the formula for the area of a triangle:

Area = (base * height) / 2

In this case, the base is AD and the height is the perpendicular distance from point M to line AD. To find the height, we can use trigonometry.

Let's calculate the area step by step:

1. Measure the length of AD using a ruler. Let's assume it measures 6 cm. 2. Measure the length of MD using a ruler. Let's assume it measures 3 cm. 3. Calculate the height of the triangle using trigonometry: - The sine of angle DAM is equal to the height divided by the hypotenuse (MD). - So, sin(25 degrees) = height / 3 cm. - Rearranging the equation, height = sin(25 degrees) * 3 cm. - Use a scientific calculator to find the value of sin(25 degrees) and calculate the height. 4. Substitute the values into the area formula and calculate the area. 5. Round the answer to two decimal places.

Please note that the exact measurements may vary based on your actual construction. Make sure to measure accurately to get the most precise results.
