Question

The width of a rectangle is represented by 5 + 2y the lingth is twice as long as the width.What is the perimeter of the rectangle?Select all correct expressions

Answer 1

Answer:

30+12y

Step-by-step explanation:

width=5+2y

length is twice its width

so 2(5+2y)=10+4y

perimeter=L+W+L+W

=2(L+W)

Therefore 2(5+2y+10+4y)

10+4y+20+8y

collect the like terms together

10+20+4y+8y

30+12y

so the answer=30+8y
