Answer 2

Answer:

The four sides of a quadrilateral are, 40 mm, 60 mm, 80 mm and 100 mm

Explanation:

4 sides of a quadrilateral are in the ratio of 2:3:4:5

Perimeter of the quadrilateral is 280 mm

Let, 4 sides of a quadrilateral be 2x, 3x, 4x and 5x

Sum of all sides = Perimeter

2x + 3x + 4x + 5x = 280  

14x = 280  

x = $\frac{280}{14}$

x = 20

∴ The value of x = 20  

Then, The four sides of a quadrilateral are,

2x = 2 × 20 = 40 mm , 3x = 3 × 20 = 60 mm , 4x = 4 × 20 = 80 mm , 5x = 5 × 20 = 100 mm  

Hence, the four sides of a quadrilateral are, 40 mm, 60 mm, 80 mm and 100 mm respectively.
