Answer 1

Step-by-step explanation:

Answer: Step-by-step explanation: The perimeter of a traingle = 48cm. 12x = 48cm.

Answer 2

Answer:

Triangle's dimensions

1st side = 12 cm

2nd side = 16 cm

3rd side = 20 cm

Step-by-step explanation:

Given -

Perimeter of triangle = 48 cm

sides of triangle (in ratio) = 3:4:5

to find -

all length of triangle

solution -

let us think triangle's sides (3:4:5) as 3x, 4x and 5x

so

=> sum of all side = perimeter

=> 3x + 4x + 5x = 48 cm

=> 12x = 48

=> x = 48÷12

=> x = 4 cm

1st side = 3x = 3×4 cm = 12 cm

2nd side = 4x = 4×4 cm = 16 cm

3rd side = 5x = 5×4 cm = 20 cm

these dimensions are in ratio 3:4:5.

hope it helps.
