Answer: The perimeter of the largest triangle = 117 units.
Step-by-step explanation:
Sides of smaller triangle = 10,20 and 15 units
Longest side = 20 units
Longest side of larger triangle = 52 units
Sides of two similar triangles are proportional.
Let k be proportionality constant.


Length of other two sides,

So sides of larger triangle = 52 units, 26 units , 39 units
Perimeter of largest triangle = 52 +26+39 = 117 units
Hence, the perimeter of the largest triangle = 117 units.
Rational numbers: B C D G
Irrational numbers: A E F
Irrational numbers are numbers that cannot be written as fractions, rational numbers are all other numbers
From the left

the function is clearly approaching 5, while from the right

it is approaching -2.
