Question

The top of Mrs. Vonvilla's coffee table has the dimensions shown. She wants to put a bumper around the edges of the table to

protect her child in case he falls. What is the perimeter of the tabletop?
48 in
28 in
Use the formula for the perimeter of a rectangle, P-2/+2w, where P is the perimeter, I is the length, and w is the width.
76 in.
152 in
304 in.

Answer 1

152 in.

Explanation:

Perimeter = 2*48 + 2*28

= 96 + 56

152 inches.

Answer 2

152 in.

Explanation:

Givens

• The dimensions of tha coffee table are
  `48in * 28in`.
• The perimeter of a rectangle is defined as
  `P=2(l+w)`, where
  `l` is the length and
  `w` is the width.

So, by given we have

`w=48in\\l=28in`

If we use the formula for the perimeter of a rectangle and substitute each variable, then we would have

`P=2(w+l)\\P=2(48in + 28in)\\P=152 in`

The perimeter of the coffee table is 152 inches.

Therefore, the right answer is the second option, 152 in.
