Question 1 Exercise 10.1

Answer:

Solution:

(a) Perimeter = Sum of all side

= 4 + 2 + 1 + 5

= 12 cm

Perimeter of fig(a) is 12 cm

(b) Perimeter = Sum of all side

= 23 + 35 + 40 + 35

= 133 cm

Perimeter of fig(b) is 133 cm.

= 15 + 15 + 15 + 15

= 60 cm

Perimeter of fig(c) is 60 cm.

(d) Perimeter = Sum of all sides

= 4 + 4 + 4 + 4 + 4

= 20 cm

Perimeter of fig(d) is 20 cm.

(e) Perimeter = Sum of all sides

= 2.5 + 2.5 + 0.5 + 0.5 + 4 + 4 + 1

= 5 + 1 + 9

= 15 cm

Perimeter of fig(e) is 15 cm.

(f) Perimeter = Sum of all side

= 4 + 1 + 3 + 2 + 3 + 4 + 1 + 3 + 2 + 3 + 4 + 1 + 3 + 2 + 3 + 4 + 1 + 3 + 2 + 3

= 52 cm

Perimeter of fig(f) is 52 cm.

hello guys welcome to Lido homework today we're doing question number one which is find the perimeter of the following figures so finding the perimeter means you just need to add the sides to find the uh length of your boundary right so let's get started with the first one the first one the sides are two one five and four so you just add so two plus one plus five plus four so five plus four is nine plus one is ten plus two is twelve so the answer to the first one is twelve centimeters let's move on to the next one or second one the second one you have 23 35 40 35 so you add them so 35 plus 35 will give you 70 70 plus 40 is 110 110 plus 23 is 133 centimeter right let's move on to the third one now the third one is 15 plus 15 plus 15 plus 15 so it's 4 times 15 15 so you can just write it as 15 into 4 which will give your answer as 60 centimeter right let's move on to d1 so d is 4 plus 4 plus 4 plus 4 plus 1 that is 5 times 4 so you can write it as 15 and uh 4 into 5 which will give your answer as 20 centimeter on here's your second then here's your third then here's your fourth so there are only fours four into four is sixteen so is sixteen then the next coming up I'm going to two centimeter now wherever you find two centimeters here is one-two centimeter second time third time uh here's your fourth time and I think that's it so two into four that will give you eight and now I have to look at three centimeters so wherever I found three centimeters here is one two three four five six seven eight so eight times I'm getting three so eight into three is twenty-four so you'll write 24 here now you just need to add all of them to get your final answer so 4 plus 16 is 20 20 plus 8 is 28 and 28 plus 24 is 52 so your final answer is 52 centimeter thank you so many guys for watching the video if you have any doubts please post it in the comment section and we'll get back to you as soon as possible also please like the video and subscribe our channel thank you so much
