Question

The figure below is formed using 2 identical squares of side 10 cm and 2 equilateral triangles. Find the perimeter of the figure.(in cm)

Answer 1

Hey bro!!

Here is your solution.....

We Have To Find Perimeter Of The Given Figure..

Perimeter means the total measure of boundary line of any geometrical figure.

Perimeter of figure = AF + FM + ME + EN + ND + DC + CB + BA.

Here ◻ABEF and ◻BEDC are square having measure of sides 10 cm.

So, In ◻ABEF
AB = BE = EF = FA = 10cm. .... (1)

In ◻ BEDC
BE = ED = DC = CB = 10cm. ..….(2)

As given that triangles ∆ FME and ∆END are equilateral triangles.

In ∆FME, EF = 10cm. .... { from (1)}
EF = FM = ME = 10cm

In ∆END, ED = 10cm. .....{from (2)}
ED = DN = NE = 10cm.


Now, Perimeter of figure = AF + FM + ME + EN + ND + DC + CB + BA.

= 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10

= 80 cm



HOPE IT HELPS YOU.....
