An umbrella is made by stitching 10 triangular pieces of clothes of 2 different colors, each piece measuring 9 cm, 40 cm and 41
malfutka [58]

Answer:

See below in bold.

Step-by-step explanation:

The triangular piece of cloth is a right triangle because 41^2 = 40^2 + 9^2 (By the Pythagoras theorem).

So the area of one piece = 1/2 * 9 * 40  cm^2.

The total amount of cloth  required for one umbrella = 10 * 1/2 * 9 * 40

= 1800 cm^2.

The total cost =  1800 * 0.25 = Rs 450.

rectangular prism has a length of 2/12 meters, a width of 4 meters, and a height of 2/14 meters. What is the volume of the prism
Natasha_Volkova [10]
The easiest way to do this, is to go ahead and convert our fractions to decimals, meaning we divide 2 by 12, and 2 by 14. This helps us have all our measurements in the same form so we can just plug them into our formula.
\frac{2}{12} =.16
\frac{2}{14} =.14
The formula for a rectangular prism is really easy:
V=L*W*H
Volume=Length times Width times Height.
.16*4*.14= 0.09 (Roughly)
Please keep in mind I only used the tenths, and hundredths place; the actual answers are much longer.
