Area of sector = ?
Computation:
Central angle = 

Area of sector = 704 cm ²
Answer:
A = 2x²; 128 ft²
Step-by-step explanation:
Area of original garden = x²
Let A = area of new garden. Then
A = 2x²
If x = 8 ft,
A = 2 × 8² = 2 × 64 = 128 ft²
The area of the new garden is 128 ft²

C is the answer for the pic
Answer:
40 ft²
Step-by-step explanation:
The shape of the outdoor carpet can be decomposed into 2 triangles and 1 rectangle
✔️Area of triangle 1:
Area = ½*bh
b = 6 - 3 = 3 ft
h = 11 - 7 = 4 ft
Area of triangle 1 = ½*3*4 = 6 ft²
✔️Area of triangle 2:
Area = ½*by
b = 2 ft
h = 3 ft
Area of triangle 2 = ½*2*3 = 3 ft
✔️Area of rectangle = L × W
L = 11 ft
W = 3 ft
Area of rectangle = 11 × 3 = 33 ft
✅area of outdoor carpet = 4 + 3 + 33 = 40 ft²
You would need to isolate the "X" variable because it is common in all 3 equations.
