Question

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

What is the area????

Answer 1

1/4 or 5/4

Explanation:

2•1 1/4= 2/1 • 5/4= 5/2 divided by 2 = 1 1/4 or 5/4

Answer 2

Area of whole rectangle = 2.5m²

Area of each piece cut = 1.25m²

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.

`(A_(rectangle))/(2) \\= (2.5m^(2) )/(2) \\= 1.25m^(2)`
