Answer:
1). Area = 37 cm²
2). Area = 120 cm²
Step-by-step explanation:
Figures in the picture attached are the examples of composite figures.
1). Area of the composite figure = Area of rectangle A + Area of rectangle B
Since area of rectangle = Length × width
Area of rectangle A = 8 × 2 = 16 cm²
Area of rectangle B = 3 × 7 = 21 cm²
Area of the composite figure = 16 + 21 = 37 cm²
2). Area of the composite figure = Area of C + Area of D
= (3×4) + (9×12)
= 12 + 108
= 120 cm²

Answer:
g = 7
Step-by-step explanation:
Given that:
Total people = students + teachers = 42 + 2
Total people = 44
Total amount = $485
Admission per person = $5
Admission of 44 persons = 44*5 = $220
Bus rental = $230
Total expense = admission + bus rental
Total expense = $220 + $230
Total expense = $450
Remaining amount = total amount - total expense
Remaining amount = $485 - $450 = $35
So if a guest is invited, it will cost $5 for admission
If g is the number of guests, the equation will be:
g($5) = $35
Dividing both sides by 5
g = 35/5
g = 7
So 7 guests can be invited
