So if QR and PQ are the same ( which they are bc the angles and other sides are the same) 3n-1= 5n-7 so -1= 2n -7 so 6 = 2n so n = 3 then QR is 5n -7 so 5 x 3 is 15-7 is 8 so the answer is 8. Hope this helps :)

Answer:
The length of the rectangle is 7.5 cm.
Step-by-step explanation:
Given that,
The width of the rectangle,
The area of the rectangle,
We need to find the length of the rectangle. The formula for the area of a rectangle is given by :
A = LB
Put all the values,
So, the length of the rectangle is 7.5 cm.
The associative property states a + (b + c) = (a + b) + c
So your answer is associative property.
