Answer 1

Answer:

The field forms two figures, a rectangle and a circle (two semicircles joined together form a circle), to figure out its area we have to use two formulas,

Area of rectangle = Length x Breadth

Area of a circle = πr²

Given = The length of the rectangle = 100 m

             The breadth of the rectangle = 28 m

             The diameter of the circle = 28 m

To find = The area of the whole figure

Solution =

First, let's find the area of the rectangle

Using the formula of the area,

Length x Breadth = 100 x 28

= 2800 m²

Now, let's find out the area of the circle,

The area of circle = πr²

The diameter is provided, and,

Radius = Diameter/2

Radius = 28/2

Radius = 14 m

Inserting this value in the formula, (take pi = 22/7)

Area of circle = 22/7 x 14²

Area of the circle = 22/7 x 196 (solving 14 squared)

Area of circle = 22 x 28 (196/7)

Area of the circle = 616 m²

Now let's add the areas of the 2 shapes together,

2800 m² + 616 m²

= 3,416 m²

The area of the field = 3,416 m²
