The areas of two similar triangles are 72dm2 and 50dm2. The sum of their perimeters is 226dm. What is the perimeter of each of t
Digiron [165]

Answer:

  • 123 3/11 dm
  • 102 8/11 dm

Step-by-step explanation:

The ratio of the linear dimensions (perimeter) is the square root of the ratio of area dimensions, so the larger : smaller ratio is ...

  √(72/50) = √1.44 = 1.2

The sum of ratio units is 1.2 + 1 = 2.2, so each ratio unit stands for ...

  (226 dm)/2.2 = 102 8/11 dm . . . . . the perimeter of the smaller triangle

Then the perimeter of the larger triangle is ...

  1.2 × 102 8/11 dm = 123 3/11 dm . . . . the perimeter of the larger triangle

Masteriza [31]

Step-by-step explanation:

\dfrac{a}{b} = \dfrac{c}{d}

Add 1 to both sides of the equation:

\dfrac{a}{b} + 1 = \dfrac{c}{d} + 1

Note that

\dfrac{a}{b} + 1 = \dfrac{a + b}{b}

Likewise,

\dfrac{c}{d} + 1 = \dfrac{c + d}{d}

Therefore,

\dfrac{a + b}{b} = \dfrac{c + d}{d}
