Answer:
4 yd².
Step-by-step explanation:
From the question given above, the following data were obtained:
Length (L) = 2⅔ yards
Width (W) = 1½ yards
Area (A) =.?
The area of the piece of fabric that Roberto needs can be obtained by using the formula for calculating the area of a rectangle. This is illustrated below:
Area (A) = Length (L) × Width (W)
A = 2⅔ × 1½
A = 8/3 × 3/2
A = 8 × ½
A = 4 yd²
Thus, the area of the piece of fabric that Roberto needs is 4 yd²
Ordered pair is 
<u>Step-by-step explanation:</u>
We have the following inequalities:
and 
. In order to find ordered pair would be a solution on the graph .Let's solve both inequalities , and will take common solution from both of them !
and , 
which implies:
⇒
⇒
⇒ 
putting value of x in both inequalities we get,
and
and 
and 
Hence at x = 
and y = 
above inequalities are satisfied. ∴ Ordered pair is
