Q: The distance between a rectangle's length and perimeter is 100 cm. What is the rectangle's width?
-
A
80 cms
-
B
90 cms
-
C
50 cms
-
D
Data inadequate
D
Answer:
D
Explanation:
Let the length of the rectangle be 'x' and breadth of the rectangle be 'y'
According to the question:
2(x + y) - x = 100
2x + 2y - x = 100
x + 2y = 100
From this we cannot find 'y' (breadth), so the given data is inadequate.
