Answer 1

See below ~

Explanation:

Finding Area

• Area = Length x Breadth
• Area = (5 - (-4)) x (0 - (-5))
• Area = 9 x 5
• Area = 45 square units

Finding Perimeter

• Perimeter = 2(Length) + 2(Breadth)
• Perimeter = 2(Length + Breadth)
• Perimeter = 2(9 + 5)
• Perimeter = 2(14) = 28 units

Answer 2

Perimeter =28 units.

Area = 45 unit^2.

Explanation:

The length of first side (joining first 2 points) = 5 - (-4) = 9 (as y coordinates are both -5)

The line joining the 2nd and third points = 0 - (-5) = 5

The line joining the 3rd and 4th points = 5 - (-4) = 9.

The line joining the first and 4th points = 0 - (-5) = 5

So the perimeter = 2(5) + 2(9)

= 28 units.

Area = 5*9 = 45 unit^2.
