Question

Area of a rectangular field is 560sq.metre.Ratio of their length &breadth is 5:7. Find the diagonal of a rectangle.

Answer 1

Hey
Since the ratios are 5:7,then let the sides be 5x and 7x.
560=5x*7x
560 = 35x²
560/35 = x²
16= x²
x = 4

Therefore the sides are:
5x = 5*4= 20m
7x = 7*4= 28m.

Let Diagnol be y
Therefore y = √(20² + 28²)
y = √(400 + 784 )
y = 35m (approx).

Hope it helps :))
