There's an obvious perpendicularity in the figure, the origin of the coordinate axes. So we put the kite's vertices on the axes so the diagonals are perpendicular. We'll make the lateral symmetry along the x axis and let the left and right be different sizes.
Answer: Kite ABCD, A(0,a), B(b,0), C(0,-a), D(-d,0)
Answer:
126 square units
Step-by-step explanation:
Area of section 1 is 8 square units which is triangle and,
Area of triangle is =
b= 2 units and height =8 units
So,
Area of section 1 =
Same Area is of section 2 which is also a triangle and has same base and height.
So,
Area of Section 2 =
Now the Area of section 3 which is square with side of 10 units
So,
Area of section 3 =
Total Area of Trapezoid =
