Answer:
Step-by-step explanation:
The width of the rectangle = x
Therefore the length of the rectangle = 2x, as it is twice its width
We know that the perimeter of a rectangle = 2 × （length + width）
So since the perimeter equals to 30, then we can form the equation:
2×(2x+x) = 30
2×(3x) = 30
6x = 30
x = 5
width of the rectangle = x = 5
length of the rectangle = 2x = 2×5 = 10
If there is an unit which is in the question, remember to add it to the end of the answer. As you have not written any units in the posted question, I will leave it as it is.
Hope this helps :)
Step-by-step explanation:
given,
perimeter (p)=30
let the length be x and breadth be x÷2 (as the length is twice of its breadth)
now, perimeter (p)=30
or, 2(l+b)=30
or, 2(x+x/2)=30
or, 6x/2=30
or, 3x=30
therefore the value of x is 10.
the dimensions are,
so, length (l)=10 breadth (b) =10/2=5...ans
hope it will help uh.
