i have a doubt please clear the doubt the question is there down.
a saree 5.5m long and 1.25 m wide has a zari border 2.5 cm broad along its length on either side . along the width on one edge the borde was 5 cm wide on the other side the zari was 25 cm wide.find the area of the zari. please help me with this answer
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 zari
Clearly, area of sari = length × breadth = 5.5 m × 1.25 m = 6.875 m2
For area of rectangle without zari, we have
length = 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.
Hope you get it!!
