Question

The side of a rectangle field are in the ratio 3:4 and its area 7500 sq meter find the perimeter​

Answer 1

let the sides be 3x and 4x

3x×4x=7500

12x^2=7500

x^2=625

x=25

3x=3×25=75

4x=4×25=100

p=2(l+b)

=2(75+100)

=2×175

=350m

Answer:

Perimeter of rectangle = 350m.

Step-by-step explanation:

The ratio given = 3:4

so, let the sides be 3x and 4x

We have also given that area of the rectangle is 7500 sq. m.

Area of the rectangle = 7500

3x × 4x = 7500

12x = 7500

x = 7500/12

x = √625

x = 25

So, the value of x is 25,

than the length is 25 × 4 = 100

and breadth is 25 × 3 = 75.

Now, Perimeter = 2(L+B)

= 2(100 + 75)

= 2(175)

= 350 ans.
