Answer:
It’s a, 49
Step-by-step explanation:
Area is length x width so you would count how long the triangle is and how wide it is so
7 x 7 is 49
The y-intercept is where it crosses the vertical axis, so -4.
The x-intercept is where it crosses the horizontal axis, so 4
You are dividing to find the answer
A+b+c=56
a=√625=25
b=2√81 = 2x9=18
c = 56-25-18=13
The answer would be C corresponding
