having trouble with this question. I need to write an equation for this word problem and also find an answer.
P = 2L + 2W
A = LW
Perimeter is given so we will use
The perimeter of a rectangle = 2*length + 2*width
Let suppose the width = x
Length = twice the width = 2x
the Perimeter = 72 = 2*2x + 2*x
72 = 4x + 2x
Now we have 72 = 6x, then dividing both sides by 6we get x = 12
So,
Width = 12 cm
Length is 12 x 2 = 24 cm
The perimeter of a rectangle is 2*length + 2*width
If we call the width x, then we can write 'The length is twice the width' as length=2x
So the perimeter = 72 = 2*2x +2*x
Collecting terms we have 72 = 6x, then dividing both sides by 6 we get x = 12
So the width is 12cm and the length is 24cm
Hope that helps!
=given,the perimeter of a rectangle=64cm
=now,the formula of a perimeter of rectangle is=2(l+w)
=the length is twise the width so, l=2w
=now we will put the given values in the formula,2(2w+w)=64cm
-> 4w+2w=64
=6w=64
=w=64/6
=w=32/3
so length of a rectangle is,l=2(32/3)
=64/3 cm
