Question

Cassandra has a rectangular patio in her backyard. the pation is 12.74 meters long and 5.45 meters wide. round the length and width to the nearest whole number then estimate the perimeter of cassandras patio write an equation to model your work.

Answer 1

Answer: Perimeter of backyard is 36 m.

Explanation:

Since we have given that

Length of rectangular backyard = 12.74 meters

Width of rectangular backyard = 5.45 meters

We need to estimate to the nearest whole number.

So, 12.74 → 13 meters

5.45 → 5 meters

So, Perimeter of rectangular backyard is given by

`2* (length+width)\\\\=2* (13+5)\\\\=2* 18\\\\=36\ m`

Hence, perimeter of backyard is 36 m.

Answer 2

12.74 rounds up to 13; 5.45 rounds down to 5. Recatangles gave 4 sides, two sides are thto same length as each other, and the other two sides are the same length as each other (which is a poor way to explain it). What that means in the context of this question is that there are two sides with length 13 and two sides length 5. So, added together 13+13+5+5 would be th total perimeter. As an expression, 2(13)+2(5)=26+10=36. The perimeter is approximately 36 meters.
