Perimeter = a + b + c = 30
Area = 1/2 x a x b = 30
Multiples of 30: 2, 3, 5, 6, 10, 12, 15
For perimeter c = 30- (a+b)
C= sqrt( a^2 + b^2)
Using the possible combinations of the above:
5 and 12:
C = sqrt(5^2 + 12^2) = 13
5 + 12 + 13 = 30 for the perimeter
Area = 1/2 x 5 x 12 = 30
The sides are 5, 12 and 13 cm
Answer:
12 cm, 5 cm, 13 cm
Step-by-step explanation:
<u>Sides of triangle:</u>
<u>Perimeter:</u>
<u>Area:</u>
<u>As per Pythagorean theorem, side c= √(a²+b²):</u>
<u>Considering ab = 60</u>
<u>Again using ab= 60 to find out sides:</u>
<u>Solving the quadratic equation, its positive root is:</u>
<u>Then we get the rest:</u>
D
You subtract the "-6" from the y, and you get +6 (which eliminates A and B). You subtract the "-2" from the x, and you get +2 (which eliminates C)
