We have a subtraction between two terms: h and 2g. Let's see the value of each term:
h is 4, it's already given.
2g means twice g, and g is 32. So, 2g is 64
So, the subtraction is

The area of the composite shape is approximately 180.53 square feet.
Answer:
78.0 ft
Step-by-step explanation:
pythagoras theorem =
a² + b² = c²
a² + 36² = 85.9²
a² + 1296 = 7378.81
a² = 7378.81 - 1296
a² = 6082.81
a = √6082.81
a = 77.992....
so, a (rounded) = 78 ft :)
