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

Answer:
x = 4
Step-by-step explanation:
The given equation is as follows :
4(3x - 6) = 24
If we want to solve the above equation, the steps are:
Using distributive property first as:
4(3x)-4(6)=24
12x-24=24
Adding 24 both sides,
12x-24+24=24+24
12x=48
x=4
So, the value of x = 4. All given steps are correct.
