Answer 1

See alternative y coordinates are equal so this is rectangle

AD

• |-3-2|
• |-5|
• 5units

BC

• 4+1
• 5units

AB

• √(-1+3)²+(2+2)²
• √4+16
• √20
• 2√5

CD

• 2√5units

Area

• LB
• 2√5(5)
• 10√5units

Answer 2

d=√((x2-x1)²+(y2-y1)²)

using above formula,

AB= 4.47

BC= 5

CD = 4.47

DA = 5

Area = L×B = 5 × 4.47 = 22.35 sq unit.
