The length of a rectangle is twice it's width. if the perimeter of the rectangle is 48 cm, find it's length and width.

Let L represent the length of the rectangle.

Let W represent the length of the rectangle.

We know that the perimeter of the rectangle is 48cm, which is equal to 2(L + W).

Therefore, L + W = 24cm.

We also know that L = 2W.

Hence, Length = 16cm and Width = 8cm.

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
