Use a ruler to measure the side length of the rectangle in centimeters mark 8 cm with a point and connect the points to show the square units then count the squares you're true to find the total area

The total area of the rectangle is found by counting the total number of 1 cm squares inside the rectangle.

Note: This question is missing some details.

A more complete question is this: Use a ruler to measure the side lengths of the rectangle in centimeters. Mark each centimeter with a point and connect the points to show the square units. Then, count the squares you drew to find the total area.

Step-by-step explanation:

This method is used to determine area of a rectangle by counting the square unit inside the given rectangle.

For example, if the measurement of the sides of the rectangle is 8 cm and 5 cm respectively. To find the area;

Step 1: Mark out 1 cm points on each side of the rectangle.

Step 2: Connect each of the points.

Step 3: Count the number  1 cm squares within the triangle. The total number of squares gives the area of the triangle.

In this example, the number of 1 cm squares will be found to be 40. So the area of the rectangle is 40 cm squares or 40 cm².

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
