I do not understand this question
These sides will form a triangle because the longest side (302) is less than the sum of the other 2 sides. http://www.1728.org/trianinq.htm
Using Heron's formula, we first have to determine the semi-perimeter of the triangle. (perimeter divided by 2)(240 + 121 + 302) / 2 = 331.50 = semi-perimeter (s)
Now, to use Heron's formula:area = square root (s • (s - a) • (s - b) • (s - c))area = square root (331.5 • (331.5 - a) • (331.5 - b) • (331.5 - c))area = square root (331.5 • (331.5 - 240) • (331.5 - 121) • (331.5 - 302))area = square root (331.5 • (331.5 - 240) • (331.5 - 121) • (331.5 - 302))area = square root (331.5 • (91.50) • (210.5) • (29.5))area = square root ( 188,355,689.44 )area = 13,724.27
Answer:
2125
Step-by-step explanation:
CP= x
MP= x+25%= 1.25x
SP= MP-15%= 1.25x*0.85= 1.0625x
SP- CP= 125
- 1.0625x-x= 125
- 0.0625x=125
- x= 125/0.0625
- x= 2000
SP= 2000+125= 2125
------------
Cost price= 2000
Marked price= 2500
Selling price= 2125
