The answer to your question is below

Step-by-step explanation:

The shape is an irregular quadrilateral shape.

Perimeter

1.- Find the length of the four sides

dAB = $\sqrt{(-5 + 25)^{2} + (-32 + 11)^{2} }$

= $\sqrt{20^{2} + 21^{2} }$

= $\sqrt{841}$

= 29 u

dAD = $\sqrt{(-4 + 25)^{2} + (9 + 11)^{2} }$

= $\sqrt{21^{2} + 20^{2} }$

= $\sqrt{441 + 400}$

= $\sqrt{841}$

= 29 units

dBC = $\sqrt{(37 + 5)^{2} + (8 + 32)^{2} }$

= $\sqrt{42^{2} + 40^{2} }$

= $\sqrt{1764 + 1600}$

= $\sqrt{3364}$

= 58 units

dCD = $\sqrt{(-4 - 37)^{2} + (9 -8)^{2} }$

= $\sqrt{-41^{2} + 1x^{2} }$

= $\sqrt{1681 + 1}$

= $\sqrt{1682}$

= 41.01 units

Perimeter = 29 + 29 + 58 + 41.01 = 157.01 ≈ 157 units

Area

To find the area divide the figure in a square and a triangle

Area of the square = 29 x 29 = 841 units²

Area of the triangle = (base x height) / 2

base = 58 - 29 = 29

height = 29

= ( 29 x 29) / 2

= 841 / 2

= 420.5 units²

Total area = 841 + 420-5 = 1261.5 units²

Determine what shape is formed for the given coordinates for abcd, and then find the perimeter and a
