Answer:
2.Length= 46m
Breadth=45m
Perimeter of rectangular yard= 2(l+b)
=2(46+45)
=182 m
Cost of fencing= 52 per meter
Cost of fencing 182 m= 182× 52
= 9464 rupees ans.
3.[] Given -
Length of the rectangular park = 200 m
Breadth of the rectangular park = 175 m
[] Then, perimeter of the rectangular park,
= 2 (length + breadth)
= 2 (200 + 175)
= 2 × 375
= 750 m
•°• Distance covered by Mr Rangan after walking once around the rectangular park = 750 m
=>> Distance covered by Mr Rangan after walking 5 times around the park,
= 5 × 750 m
= 3750 m
= 3.75 km.
Hence the total distance covered by ranjan was 3km 750m
4.Wood required for making one frame = perimeter of picture
=2(l + b)=2(4+3) =2 * 7 =14 m
Length of Wood required for 10 pictures =14 * 10 =140m
5.Since we are given that The perimeter of a regular pentagon is 100 cm. Length of each side is 20 cm. Hence the length of the side of the regular pentagon is 20 cm.
6.The length of wire needed is 1200 m
Step-by-step explanation:
Side of square = 100 m
Perimeter of square = 4 \times Side =
Length of fence all around in 1 layer = 400 m
Length of fence all around in 3 layers =
Hence the length of wire needed is 1200 m
A square piece of land has each side equal to 150 M if three layers of metal wire to be used to fence if then what is the length of wire needed
7) 2 x ( 150 + 125 )
2 x 275
550 m is the perimeter
8.Idk
9. length=320m
breath= 10m
total walk=perimeter of rectangle
=2(l+b)
=2(320+10)
=2(330)
=660m
660mper 1round
distance covered in 23 rounds
23×660
15180m
the total distance covered by in the morning walk is 15180m
10. Idk
11.lenglth is 2m 50cm
because the longness of a object is same as length
12.Carpet Length : 5m 20cm = 520 CM
Carpet Breadth : 3m 20cm = 320 CM
Perimeter of Carpet : 2 ( L + B )
= 2 (520+320) CM
= 2×840 CM
= 1680 CM
= 16.8 Metre
13.The answer will be 321 cm.
Step-by-step explanation:
we have given that;
breadth = 53.5 cm;
length = 2 (breadth);
= 2 (53.5);
= 107.0 cm;
Now perimeter of a rectangle is equal to ;
= 2(l + b);
Now, put he value in the formula;
= 2 (107 + 53.5);
= 2 (160.5);
= 321.0 cm
14.Answer: (a). 7.5 cm, (b) 10 cm and (c) 5 cm.
Step-by-step explanation: The length of the string is given to be 30 cm.
To find the length of a regular polygon by using the string, we first need to know the number of sides of the polygon, and the we will divide the length of the string the number of equal sides of the polygon.
(a) For a square, the number of equal sides = 4. So, the length of each side of the square is given by
(b) For an equilateral triangle, the number of equal sides = 3. So, the length of each side of the equilateral triangle is given by
(c) For a regular hexagon, the number of equal sides = 6. So, the length of each side is given by
Thus, the answer is 7.5 cm, 10 cm and 5 cm.
15.Perimeter of hexagon = 6 × side
Given Side = 12 m
Perimeter = 6 × 12 m
= 72 m
∵ Perimeter of the given hexagon is 72 m.
