Answer:

23,23,200 Sq.m

Step-by-step explanation:

The ratio of sides of right angled triangle in this case will 3:4:5

============

using Pythagoras theorem -  sum of square of each side = square of hypotenuse in case of right angled triangle.

a²+b² = c²   => 9x² + 16x² = 25x²

=> c = 5x

==============

Now

Length = 4x

Breadth = 3x

Hypotenuse = 5x

5x = 2200 m

x = 2200/5 = 440 m.

=> Length = 4* 440 = 1760 m; Breadth = 3*440 = 1320 m.

Area = L*B = 1760 * 1320 = 23,23,200 Sq.m

Step-by-step explanation:

Let ,

Length = 4x

Breadth = 3x

diagonal = 2200 m

therefore, by Pythagoras theorem

(2200)sq = (4x)sq + (3x)sq

4840000 = 16x sq + 9x sq

4840000 = 25x sq

4840000÷25= x sq

x sq = 193600

x. = 440 m

therefore,

Length = 4 × 440 = 1760m

Breadth = 3 × 440 = 1320m

Area of rectangular field = L × B

A. = 1760 × 1320

A = 2323200m sq.
