Question

find the area of square whose perimeter and area are in the ratio 3 ratio 4​

Answer 1

Answer:

Answer

Let side of the square be l.

then from the question 

4l=l2

l=4

Let length and  width of the rectangle be a and b

then 

from the question 

2(a+b)=ab

ab−2a=ab

a=b−22b

keep b=3 and b=4 then we get a=6and a=4

Since, a=b=4 is a square

we take a perfect rectangle a=6 and b=3

Answer 2

Let the side of the square be = x

Area of the square = side × side = x²

Perimeter of the square = 4 × side = 4x

Perimeter of square = 3

Area of square 4

4x = 3

x² 4

x = 4 × 4

3

x = 16/3

x = 5.33

Area of the square = x²

= 5.33 × 5.33

= 28.4 square units
