Question

the length and breadth of a rectangular field are in the ratio 4:3 if the area is 6.75 hectares then the side of the field are ____?

Answer 1

Heya !!!





Let length of rectangle be 4X and breadth of rectangle be 3X.




Area of rectangle = 6.75 hectares



L × B = 6.75



4X × 3X = 6.75


12X = 6.75


X = 6.75/12

X = 0.5625 hectare




Length of rectangle = 4X = 4 × 0.5625 = 2.25 hectares


And,

Breadth of rectangle = 3X = 3×0.5625 = 1.68 hectares.

Answer 2

Let the unknown value be 'x'

4x and 3x 
Area = 6.75 hectares = 6.75 × 10000 = 67500 sq. m
4x × 3x = 67500
12x² = 67500
x² = 5625
x = √5625
x = 75 
∴ 4x = 4×75 = 300 metres
3x = 3×75 = 225 metres
