Answer:
D 30+ 12y
Step-by-step explanation:
A rectangle has 4 sides. The opposite sides are equal in size for rectangle . The width which are opposites have same size while the length has same size.
According to the question the width is represented by 5 + 2y
width = 5 + 2y
The length is twice the size of the width which means 2 times the width value.
length = 2(5 + 2y)
The perimeter of the rectangle can be computed when you sum the whole side of the rectangle . The formula can be represented as
Perimeter = L + L + W + W = 2L + 2W = 2(L + W)
perimeter = 2(2(5 + 2y) + 5 + 2y)
perimeter = 2(10 + 4y + 5 + 2y)
perimeter = 2(15 + 6y)
perimeter = 30 + 12y
