Question

Find the area of rectangle ABCD.
20
10 √2+ √82
24
12

Answer 1

So I did the assignment, and the answer that you're looking for in this problem would be 12.

Answer 2

12 units²

Explanation:

AB =
`\sqrt{(x_(2) -x_(1))^2 +(y_(2) -y_(1))^2 }` =
`√((0-3)^2 +(0-3)^2)` = 3√2

BC =
`√((5-3)^2 +(1-3)^2)` = 2√2

`A_(ABCD)` = AB × BC = 3√2 × 2√2 = 12 units²
