Question

Bridgette made a graph of her neighborhood on a coordinate grid. The points A(-2, 3), B(-2, -2), C(2, -2), and D(2, 3) represent her daily jogging path. She starts at her house, point A, then she jogs to points B, C, and D before returning home. If each space on the coordinate grid represents 1 block, how many blocks does she jog?

Answer 1

`\boxed{\text{18 blocks}}`

Explanation:

Distance travelled on graph = AB + BC + CD + DA

AB = CD = (3 +2) = 5

BC = AD = 2 –(-2) = 4

Distance on graph = 2 × 5 + 2 × 4 = 10 + 8 = 18 spaces = 18 blocks

Bridgette jogs
`\boxed{\textbf{18 blocks}}`each day.
