Question

For the given problem, choose the correct expression for the length of the rectangle.
The length of a rectangle is 2 less than 3 time as long as width.
If the perimeter is 76 cm, find the dimensions of the rectangle

Answer 1

Therefore Width = (76-4)/6 = 12 cm, Length = 2X12 + 2 = 26 cm

Step-by-step explanation:

Perimeter = 2 X (Length + Width),  Length = 2 X Width + 2 cm, Perimeter = 2 X (2XWidth+ 2 cm + Width) = 76

Therefore Width = (76-4)/6 = 12 cm, Length = 2X12 + 2 = 26 cm

Answer 2

Answer:

given,

length=x

width=y

x=3y-2

perimeter of rectangle=2×( length + width)

76=2×(3y-2+y)

76=2×(4y-2)

38=4y-2

4y=36

y=9

x=3y-2

x=3×9-2

x=27-2

x=25

length=25

width=9
