Answer:
28 cm²
Step-by-step explanation:
The area of Δ BDF is the area of the rectangle subtract the area of the 3 white triangles.
Since the area of the rectangle = 80 cm² and
area = length × breadth, then
breadth = 80 ÷ 10 = 8 cm
Thus CE = EF = 8 cm and CD = DE = BC = 4 cm
Area of Δ DEF = 0.5 × 10 × 4 = 20 cm²
Area of Δ ABF = 0.5 × 8 × (10 - 4) = 0.5 × 8 × 6 = 24 cm²
Area of Δ BCD = 0.5 × 4 × 4 = 8 cm²
Thus
area of Δ BDF = 80 - (20 + 24 + 8) = 80 - 52 = 28 cm²
I’m pretty sure the answer to this is 1,932,934.

Answer:
4.75 cups of food.
Step-by-step explanation:
convert the mixed numbers to decimals. 10 3/4 is 10.75, 5 1/2 is 5.5. add them together 10.75 + 5.5 + 2.75 = 19. 19 / 4 = 4.75
