a field is rectangular in shape and its lenght is 1 1/2 times its breath . if its area is 2.4576 hectares . what is its perimeter |
Answer» Answer :
Given :
To find :
Solution :Given length is 1 ½ times its breadth so ,
Area is 2.4576 hectares
》2.4576 × 10000 》24576 m² Area is 24576m² As we know that ,
》24576 = 3/2 x × x 》x² = 24576 × 2/3 》x² = 16384 》x = √16384 》x = 128 HENCE , Breadth is 128
Now we have to find the perimeter: As we know that ,
Where, l is length 192 and b is breadth 128 》Perimeter of rectangle = 2(length + breadth) 》2(192 + 128) 》2(320) 》640m Hence , Perimeter is 640m Verification : Given
As we know that,
》Area of rectangle = length × breadth 》192 × 128 》24576 m² Hence verified |

The length of a minute hand of a wall-clock is 10.5 cm. Find the distance coveredby tip of minute hand in 2 hours. |
|
Answer» Answer:
Step-by-step explanation:
To Find:-
Solution:- If the minute hand takes 1 hour to complete one round .So , the number of rounds covered by minutes hand is 2 As we have to calculate the TOTAL distance covered by the minute hand so we calculate the circumference or PERIMETER of the clock .
where,
Substitute the VALUE we get → Total distance covered by minute hand = 2 × 2 πr → Total distance covered by minute hand = 2× 2 × 3.14 × 10.5 → Total distance covered by minute hand = 4 × 3.14 × 10.5 → Total distance covered by minute hand = 131. 88 cm
