Question

Jordan is cutting a 2m by 1 1/4 piece of rectangular paper into two pieces along its diagonal.

Answer 1

Answer:

Area of whole rectangle = 2.5m²

Area of each piece cut = 1.25m²

Step-by-step explanation:

The formula for the area of a rectangle is length times width $A = (l )(w)$.

The length is 2m and the width is 1 1/4 m, or 1.25m.

Substitute length and width into the formula to get total area of rectangle.

A = L x W

A = 2m x 1.25m

A = 2.5m²

To find the area for each of the two pieces Jordan cut, divide the total area by 2 because there are two pieces.

$\frac{A_{rectangle}}{2} \\= \frac{2.5m^{2} }{2} \\= 1.25m^{2}$
