The shape represents a rectangle, a small triangle removed from it at the upper right corner and a bigger triangle is attached to it at the upper left corner.
We get this formula: A(shape) = A(rectangle) - A(small triangle) + A(big triangle) SO LET'S FIND EACH!
A(rectangle)= length x width length= 8 units width= 4 units We get: A(rectangle) =8x4= 32 square unit
A(small triangle)= (base x height)/2 base= 1 unit height= 1 unit We get: A(small triangle) = (1x1)/2 = 1/2 = 0.5 square units
A(big triangle)= (base x height)/2 base= 2 units height= 4units We get: A(big triangle)= (2x4)/2 = 8/2 = 4 square units
For the final result: A(shape) = 32 - 0.5 + 4 = 35.5 square units
