Answer:
46 cm²
Step-by-step explanation:
Given: ANB is a straight line
AN= 9 cm
NB= 5 cm
Are of rectangle( ANCD)= 36 cm²
Now finding the length of rectangle ANCD.
Lets assume the length of rectangle be "l"
Area of rectangle=
⇒
dividing both side by 9 cm.
∴
Hence, NC= 4 cm
Next, finding the area of triangle ΔNBC
Area of triangle=
⇒ Δ NBC=
∴Δ NBC= 10 cm²
We know, the area of ANCD= 36 cm²
∴ Area of ABCD= Area of rectangle+area of triangle
⇒Area of ABCD= 36+10
∴ Area of ABCD= 46 cm²
Answer:
After 1.5 hours
Step-by-step explanation:
The truck and the car are moving in the same direction after they left the service station at the same time. The truck travels at 52 miles per hour and the car at 44 miles per hour.
Let us assume that after h hours their distance from each other will be 12 miles.
So, 52h - 44h = 12
⇒ 8h = 12
⇒ h = 1.5 hours.
Therefore, after 1.5 hours their distance from each other will be more than 12 miles and their radio contact will be lost after that. (Answer)
