Answer:
The Area is 25
Step-by-step explanation:
You will need distance formula for this questions
for AD, (0,4) and (4,7)
The formula is here
[tex]\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
which gives you
[tex]\sqrt{\left(4-0\right)^2+\left(7-4\right)^2} = 5[/tex]
for AB
(0,4),(3,0)
[tex]\sqrt{\left(3-0\right)^2+\left(0-4\right)^2}=5[/tex]
The answer will be 5*5, which is 25
