Question

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

Answer 1

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

Area of the rectangle = length × width

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

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

Diagonal of a rectangle divides it into two equal parts.

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