A saree 45 m long long and 1.2m wide has a 25 cm wide Border all around it on the inside. Find the cost of weaving the border at the rate of 15 paise per sq.com. -
Answers
Answer:
0.635 m2
Step-by-step explanation:
The given conditions can be summed in a figure as shown below.
Area of zari = Area of outer rectangle (or sari) - Area of rectangle without zariClearly,
area of sari = length × breadth = 5.5 m × 1.25 m
= 6.875 m2
For area of rectangle without zari, we havelength = 5.5 m - (5 cm + 25 cm) = 5.5 m - 30 cm = 5.5 m - 0.3 m [Using 100 cm = 1 m]
= 5.2 m
Similarly, its breadth = 1.25 m - (2.5 cm + 2.5 cm)
= 1.25 m - 5 cm
= 1.25 - 0.05 m
[Again, using 100 cm = 1 m]= 1.2 m
Therefore, area of sari without zari = length × breadth= 5.2 m × 1.2 m = 6.24 m2
So, the area of zari = Area of outer rectangle (or sari) - Area of rectangle without zari= 6.875 m2 - 6.24 m2 = 0.635 m2
Hence, the area of zari is 0.635 m2.
Answer:
As we all know saree is in the shape of rectangle,
therefore,
area of border= (area of outer rectangle) - (area of inner rectangle)
--> area of border = (45 × 1.2) - (44.5 × 0.7)
--> area of border = 54 - 31.15
--> area of border = 22.85 m²
Now we have calculate the cost,
as per question, cost of 1 sq. m is 15 paise.
therefore,
cost of 22.85 sq.m is
--> 22.85 × 15
--> 342.75 paise
