Question

3. Trudy wants to surround her garden on all four sides with fencing. Her rectangular garden is 270 cm by 130 cm. How many meters of fencing will she need?

Answer 1

9514 1404 393

Answer:

  8 m

Step-by-step explanation:

There are 100 cm in 1 m, so the dimensions of Trudy's garden are 2.7 m by 1.3 m. The perimeter is double the sum of those measures:

  P = 2(L +W)

  P = 2(2.7 m + 1.3 m) = 2(4.0 m)

  P = 8.0 m

Trudy will need 8 meters of fencing to surround her garden.
