Answers

Answer:

5/4 m²

Step-by-step explanation:

Jordan is cutting 2 m by 1 1/4 m piece of rectangular paper into 2 pieces along its diagonal.What is the area of each of the pieces.

Length of the rectangular paper = 2m

width of the rectangular paper = 1 1/4m

Area of a rectangle = Length × width

= 2 × 1 1/4

= 2 × 5/4

= (2 * 5)/4

= 10/4 m²

Area of a rectangle = 10/4 m²

Diagonal divides the rectangle into 2 equal pieces

Divide area of the rectangle by 2

Area of each piece of the diagonal = Area of the rectangle / 2

= 10/4 m² / 2

= 10/4 ÷ 2

= 10/4 × 1/2

= (10*1) / (4*2)

= 10/8

= 5/4 m²

Area of each piece of the diagonal = 5/4 m²
