Question

the perimeter of the triangle is 80m . if their sides of the triangle in the ratio 2:3:4 . find the length of each sides​

Answer 1

Step-by-step explanation:

let the common multiple be X

2x+3x+4x =80

9x =80

x=80/9

X=8.888m

2x=8.88×2 =17.76m

3x=8.88×3=26.64m

4x=8.88×4=35.52m

Answer 2

Given :-

• The perimeter of the triangle is 80m
• Sides of the triangle in the ratio 2:3:4

To find :-

• Length of each sides of triangle

Solution :-

Let the side of triangle be x

➩ Perimeter of triangle = 80

➩ 2x + 3x + 4x = 80

➩ 9x = 80

➩ x = 80/9

➩ x = 8.8cm

Hence,

• Sides of triangle
• 2x = 2*8.8 = 17.6 cm
• 3x = 3*8.8 = 26.4 cm
• 4x = 4*8.8 = 35.2 cm

Additional Information

• Area of rectangle = length × breadth
• Area of square = side × side
• Perimeter of square = 4 × side
• Perimeter of rectangle = 2(length + breadth)
