Question

The four corners of a rectangular city block are located at (-5, -2).(-5,9), (9,9), and(9, -2) on the coordinate grid below. Randy walks all the way around the block and stopswhen he gets back to where he started. Each unit on the grid represents 10 meters. Howmany meters does Randy walk? Type the answer in the box below.ol987654321--10-9-8-7-6-5-4-3-2-1-1 2 3 4 567 8 9 10-34-5-6-7-8-9-10meters

Answer 1

Plot the four vertices of the rectangle using the given coordinates:

Find the perimeter of the rectangle by adding the length of each side.

The sides of that rectangle have lengths of 14, 11, 14 and 11 units. Then, the perimeter of the rectangle is:

$14+11+14+11=50$

Since each unit on the grid represents 10 meters, multiply that result by 10 to find the real distance that Randy walked, measured in meters:

$50\times10m=500m$

Therefore, the answer is:

$500\text{ meters}$
