Question

The question is: Select all the options that are true about the area and perimeter of the park( round the area to the nearest 100 and the perimeter to the nearest 10 feet). The answers: A: The area of the park is 3200 square feet B: The area of the park is 3400 square feet C: The area of the park is 4400 square feet D: The perimeter of the park is 240 feet E: The perimeter of the park is 250 feet F: The perimeter of the park is 300 feet

Answer 1

Given:

The rectangle is shown in the figure with length= 8 units

and breadth=4 units

This you can get from the graph since, length can be calculated horizontally as we are going from (-9,0) to (-1,-2) and similarly we can calculate the breadth vertically as we are going from (-9,0) to (-8,4).

So the length = 8 units or grids and breadth = 4 units or grids.

Now, the area of the park is given by:

`\text{Area}=\text{length}* breadth`

Substituting the value, we get:

`\begin{gathered} A\text{rea}=8*4 \\ =32\text{ grids} \end{gathered}`

Since, in the question we are given that each grid is of 100 square feet so we will multipy the number of grids of area by 100 to get the whole area.
