perimeter of a rectangle having 16 cm length is 50 cm. find its breadth.
Answers
Step-by-step explanation:
perimeter = (l + b)2
50 = (16+ b)2
50 = 32 + 2b
50 - 32 = 2b
2b = 18
b = 9
Answer:
Hence, the breath of rectangle is 9cm.
Step-by-step explanation:
As per the data given in the above question.
The given data is as follows.
The perimeter of a rectangle is 50cm
And the length of a rectangle is 16cm.
We have to find the breath of a rectangle.
As we know that,
Perimeter of a rectangle= 2(length + breath)
Substituting the value of length and perimeter
We get,
=50=2(16+ breath)
We will multiply bracket by 2.
We get,
=50=32+ 2breath
Now, we will shift the 32 of RHS to LHS as it is positive it will become negative.
We get,
=50-32= 2breath
We will subtract 32 from 50
=18=2breath
We will shift numerator 2 of RHS to the denominator of LHS.
We get,
[tex]breath=\frac{18}{2} \\ =9cm.[/tex]
Hence, the breath of rectangle is 9cm.
