Answer:
The new triangle will have a perimeter of 36 cm, and an area of 18 cm2.
Step-by-step explanation:
Given that the triangle whose perimeter is 12 cm and its surface is 6 cm2, and is lengthened by a scale factor of 3 to produce a similar triangle, the perimeter and surface of the new triangle arise from the following calculation:
Perimeter = 12 x 3 = 36 cm
Area = 6 x 3 = 18 cm2
Thus, the new triangle will have a perimeter of 36 cm, and an area of 18 cm2.
Answer: V - 15 = 74; V = 89
<u>Step-by-step explanation:</u>
"difference" means subtraction
"is" means equals
Vidya's height <u>minus</u> 15 <u>is</u> 74
V - 15 = 74
To solve, add 15 to both sides: V - 15 + 15 = 74 + 15
V = 89
A Pythagorean triple is a triple that describes the three positive integer side lengths of a right triangle. It fits the rule a^2 + b^2 = c^2. From the given sets of numbers above, the following are the Pythagorean triples: Option C: 12, 16 and 20 (144 + 256 = 400); Option E: 8, 15 and 17 (64 + 225 = 289); and Option F 32, 60 and 68 (1,024 + 3600 = 4,624).
