Someone explain to me how to find the area ! find the area and perimeter of quadrilateral abcd below. explain your process for finding both the area and the perimeter, and show your mathematical steps clearly.

Part A) The area of the figure is

Part B) The perimeter of the figure is

Step-by-step explanation:

step 1

Find the area of the figure

we know that

The area of the figure is equal to the area of triangle ABD plus the area of triangle BCD

The area of triangle is equal to

Area of triangle ABD

Observing the graph

substitute

Area of triangle BCD

Observing the graph

substitute

The area of the figure is

step 2

Find the perimeter of the figure

we know that

The perimeter of the figure is equal to

we have

the formula to calculate the distance between two points is equal to

Find the distance AB

Find the distance BC

Find the distance CD

Find the distance AD

substitute the values

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,

mrb

hi there!

the answer will be d: 2
