Question

a die is thrown 15 times and outcomes are observed as 1,6,6,5,3,2,3,2,4,4,2,1,5,6,2 prepare a bar graph and hence find out that which outcome is most probable​

Answer 1

Step-by-step explanation:

Let length =5x and breadth=2x

Area of rectangle=5x×2x=10x2

Perimeter of rectangle=2(l+b)=2×(5x+2x)=14x

Now, AP=31⇒10x214x=31⇒x=4.2

∴Length of rectangle=5×4.2=21 units
