Question

1. Statement A: In a rectangle, if area remains
constant, the length and breadth are in
direct proportion.
Statement B: The number of ice-cream cups
and their total cost are in direct proportion.
(a) Both A and B are true.
(b) Both A and B are false.
c) A is true and B is false.
(d) A is false and B is true
​

Answer 1

Answer:

d) a is false and b is true

:/ i think

Answer 2

Answer:

A is incorrect.

B is correct.

Step-by-step explanation:

A Explanation

Suppose if area of rectangle is 24 meter square with length 3m and breadth 8m. Now, if we want area constant one of these two quantities, either length will increase and breadth will decrease or vice versa i.e.

L =4m

B= 6m

Area =24 meter square

or

L =2m

B =12m

Area =24 meter square

From above example one can easily understand if we are to keep area of rectangle constant then one from length and breadth is increased and other is decreased. So its inverse relation.

B Explanation

More the number of cups of ice cream, more will be cost. That's pretty simple.
