Explanation

• 1. The ratio of length to breadth is 3:2. Let's assume the length is 3x and the breadth is 2x.
• 2. The perimeter of the rectangular park is 2(3x + 2x) = 10x.
• 3. The man completes one round in 8 minutes at a speed of 12 km/hr. Convert the speed to meters per minute:

12 km/hr = 12,000 m/60 min = 200 m/min

• 1. The distance covered in 8 minutes is:

200 m/min × 8 min = 1600 m
Since the man completes one round, the perimeter of the park is 1600 m:
10x = 1600
x = 160
Now, find the length and breadth:
Length = 3x = 3 × 160 = 480 m
Breadth = 2x = 2 × 160 = 320 m
Finally, calculate the area:
Area = Length × Breadth = 480 × 320 = 153,600 sq. m

Explanation

Square (regular quadrilateral):

all four sides are of equal length (equilateral), and all four angles are right angles. 

A triangle that has no equal sides and no equal angles is known as a Scalene Triangle

while 

if two sides of a triangle are of equal length, then it is called. Isosceles triangle

Explanation

A circle is divided into 360 equal parts, with each part measuring 1 degree.

When you combine all 360 parts, you complete a full circle, hence 360°.

Explanation

The area of a rectangle is calculated by multiplying its length by its breadth:

Area = Length × Breadth

= 16 cm × 3 cm

= 48 cm²

Explanation

One nautical mile per hour is equal to 1 knot.

One nautical mile is equal to 6,076 feet (1,852 meters/kilometers).
