Given:
Parallelogram length = 11 cm
triangle atop the parallelogram : short leg = 7 cm
Right triangle inside the parallelogram : long leg = 9cm
Area of parallelogram = base * height
A = 11cm * 9cm
A = 99 cm²
Area of a triangle atop the parallelogram:
A = ab/2
A = (11cm * 7cm)/2
A = 77 cm² / 2
A = 38.5 cm²
Total area of the figure
99 cm² + 38.5 cm² = 137.5 cm²
I believe it’s 70 because a straight like always adds up to 180 so 180-110=70
