Question

4:7:9. The perimeter of the triangle is 120 feet. Find the length of the smallest side

Answer 1

Step-by-step explanation:

4x+7x+9x = 120

20x = 120

x = 120/20

x = 6

4x = 6×4 =24

24 is correct answer

Answer 2

Answer:

Smallest side = 24 feet.

4:7:9 = 120

4x + 7x + 9x = 120

20x = 120

x = 120/20

x = 6

Now, the smallest side is 4x,

So, 4 × x =

Smallest side = 4 × 6 = 24 feet

by above we can find other sides also.
