What do you mean? i don’t quite get this question
The area of a triangle is base * height / 2
The length of the base is 16 - 12 = 4
The height is 31 - 0 =0
Then the area is 4*31/2 = 62
In order to calculate the length of highest piece, You need to calculate the Greatest common divisor of 672 & 960 which is 96
So, the length of highest piece would be 96 cm
Now, Number of pieces of Iron-sheet = 672 / 96 = 7
Number of pieces of Copper-sheet = 960 / 96 = 10
Hope this helps!
If we are to make x small rugs, each of which takes 2 hours to dye, then the total time taken to dye the small rugs is 2x. Similarly for the y large rugs which each take 3 hours to dye, the total time for dyeing the large rugs is 3y. Therefore the total for all sizes of rugs is 2x + 3y. Finally, we have a maximum of 60 available hours for the dyeing, so the total time cannot exceed 60, and the final inequality is
2x + 3y < 60
8x + 2 + 70 + 60 = 180
8x + 132 = 180
180 - 132 = 48
48/6 = 6
X = 6
