Jordan is cutting a 2 meter by 1 1/4 meter into two pieces by its diagonal line
Airida [17]

Question:

Jordan is cutting a 2 meter by 1\frac{1}{4} meter piece of rectangular paper into two pieces along its diagonal. what is the area of each of the pieces?

Answer:

Area of each piece of paper is 1 \frac{1}{4} \ m^2.

Solution:

Length of the paper = 2 m

Width of the paper =  1\frac{1}{4} m =  \frac{5}{4} m

<em>Area of the rectangle = length × width</em>

                                    $=2\times \frac{5}{4}

                                    $= \frac{5}{2} \ m^2

<em>Diagonal of a rectangle divides it into two equal parts.</em>

Area of each piece = Area of the rectangle ÷ 2

                                $=\frac{ \frac{5}{2}}{2}

                                $=\frac{5}{4} \ m^2

                                $=1 \frac{1}{4} \ m^2

Area of each piece of paper is 1 \frac{1}{4} \ m^2.
