I don’t know about the slope but the Y-Intercept is just the Y.
To find the regular follow this formula ; area = 1/2 x perimeter x apothem. Which means ... perimeter = the sum of lengths of the all sides
Answer:
64 square inches
Step-by-step explanation:
You can split this figure into a rectangle and triangle to find the area.
A= l * w
A= 5 * 12
Area of the rectangle = 60 sq in
A= 1/2 bh
b= 12-8 = 4
h= 7-5 =2
A= 1/2 (4)(2)
Area of the triangle = 4 sq in
60 + 4 = 64 sq in
