If length and width of a rectangle are in the ratio 4 to 5 and the perimeter of the rectangle is 144, find the dimensions of the rectangle.

So dimension of rectangle are :

Length =  32

Width =  40

Step-by-step explanation:

Let the length of rectangle be 4x and width of rectangle be 5x.

Remember ratio of length and width is 4 to 5.

Perimeter of rectangle is given as 144.

i.e 2 (length +width) = 144

or 2 ( 4x + 5x ) = 144

Solving this for x, we get :

or 9x = 144/2

or 9x = 72

or x = 72/9

or x = 8

So dimension of rectangle are :

Length = 4 x = 4*8 = 32

Width = 5x = 5*8 = 40

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
