30

Explanation:

count the cubes

Answer 2

The answer to your question is Perimeter = 26 units

Explanation:

Data

Vertex

A(-2, 3)

B (4, 7)

C (7, -1)

Process

1.- Find the distance between the vertex

dAB =
`\sqrt{(4 + 2)^(2) + (7-3)^(2)}`

dAB =
`\sqrt{6^(2)+ 4^(2)}`

dAB =
`√(36 + 16)`

dAB =
`√(52)`

dBC =
`\sqrt{(7-4)^(2) + (-1 -7)^(2)}`

dBC =
`\sqrt{3^(2) + 8^(2)}`

dBC =
`√(9 + 64)`

dBC =
`√(73)`

dAC =
`\sqrt{(7 + 2)^(2)+ (-1-3)^(2)}`

dAC =
`\sqrt{9^(2) + 4^(2)}`

dAC =
`√(81 + 16)`

dAC =
`√(97)`

Perimeter =
`√(52) + √(73) + √(97)`

Perimeter = 7.21 + 8.54 + 9.84

Perimeter = 25.59 ≈ 26 units
