Question

Two sides of a triangular plot of land are of length 28m 25 cm and
23 m 75 cm. If the perimeter of the plot is 78 m 25 cm, then find the
length of the third side of the plot.​

Answer 1

Answer:

26m 25cm

Step-by-step explanation:

add both sides and subtract it from perimeter and you will get your answer.

just like below

let third side be x

28.25+23.75+x =78.25

x=78.25-52

x=26.25

The length of third side is 26 m 25 cm

Hope this helps you

Answer 2

Answer:

Length of the third side of the plot is 2625 cm    

Step-by-step explanation:

Given data

Two sides of a triangular plot of a land are 28 m 25 cm and 23 m 75 cm

⇒ 28 m 25 cm = 2800 cm +25 cm = 2825 cm    [∵ 1 meter = 100 cm]

⇒ 23 m 75 cm = 2300 cm + 75 cm =  2375 cm   [∵ 1 meter = 100 cm]

the perimeter of the plot = 78 m 25 cm  

⇒ 78 m 25 cm = 7800 + 25 cm = 7825 cm

here we need to find length of the third side of the plot

⇒ let x be the length of the third side of the plot

⇒ from given data perimeter of the plot = 7825 cm

⇒ 2825 cm + 2375 cm + x = 7825 cm

⇒ 5200 cm + x = 7825  cm

⇒ x = 2625 cm

⇒ length of the third side of the plot = 2625 cm
