Question

the side of triangle are in the ratio 3 ratio 5 ratio 7 and its perimeter is 300 metre find its area​

Answer 1

Answer:

60,100,140

Step-by-step explanation:

$let \: each \: side \: be \: x \\ ratio = 3.5.7 \\perimeter = 300 \\ according \: to \: the \: question \\ 3x + 5x + 7x = 300 \\ 15x = 300 \\ x = \frac{300}{15 } \\ x = 20 \\ 1side = 3 \times x = 3 \times 20 = 60 \\ 2side = 5x = 5 \times 20 = 100 \\ 3side = 7x = 7 \times 20 = 140$
