Answer 2

Answer:

Width of the path = 2.5 m

Length of rectangular park = 20 m

Breadth of the rectangular park = 15 m

To Find :-

The area of the path.

Analysis :-

Find the area of the smaller rectangle.

Add the width of the path to the length and breadth and find the area of the bigger rectangle.

Subtract the area of smaller rectangle from the bigger rectangle to find the area of the path.

Solution :-

We know that,

l = Length

b = Breadth

a = Area

Given that,

Length (l) = 20 m

Breadth (b) = 15 m

By the formula,

Area of a rectangle=Length×Breadth

Substituting their values,

Area = 20×15

Area = 300 m²

Therefore, the area of the rectangle excluding the path is 300 m²

Now,

Area of the rectangle including the path = (Length + 2.5 m) × (Breadth + 2.5 m)

Substituting them,

Area = (20+2.5) ×(15+2.5)

Area = 22.5×17.5

Area = 393.75 m²

Therefore, the area of the rectangle including the path is 393.75 m²

Finding the area of path,

Area of path = Area of bigger rectangle - Area of smaller rectangle

Substituting them,

Area of path = 393.75-300

Area of path = 93.75m²

Therefore, the area of path is 93.75 m².
