Mensuration:

Mensuration is the branch of mathematics which concerns itself with the measurement of Lengths, areas & volume of different geometrical shapes or figures.

Plane Figure: A figure which lies in a plane is called a plane figure.

For e.g:  a rectangle, square, a rhombus, a parallelogram, a trapezium.

 

Perimeter:

The perimeter of a closed plane figure is the total length of its boundary.

In case of a triangle or a polygon the perimeter is  the sum of the length of its sides.

Unit of perimeter is a centimetre  (cm), metre(m) kilometre(km) e.t.c

Area: The area of the plane figure is the measure of the surface enclose by its boundary.

 

The area of a triangle are a polygon is the measure of the surface enclosed by its sides.

A square centimetre (cm²) is generally taken at the standard unit of an area. We use square metre (m²) also for the units of area.

Circumference of a circle is the perimeter of a circle.

In a circle the radius is half of the diameter.

The approximate value of π( Pi) is= 22/7

Hi my lil bunny!

❀ _____.______❀_______._____ ❀

Given:

⇒ D = 7cm

∴ R = 3.5cm

⇒ Combined circumference of semi circles = 2\pi R = 2  X \frac{22}{7} X 3.5 = 22m

⇒ Length = 20 - 3.5 - 3.5 = 13

⇒ Perimeter = 13 + 22 + 13 = 48m

⇒ Area = 13 X 7 + \frac{22}{7}  X 3.5^2 = 129.5 meters
