Question

Find the value of x if in a rectangle area=572 units length=11x breadth=13x units

Answer 1

$11x \times 13x = 572 \\ {x}^{2} = \frac{572}{11 \times 13} \\ \\ = > {x}^{2} = 4 \\ x = \sqrt[]{4} \\ x = 2$

Answer 2

Area of rectangle=l×b
572 unit sq.=(11x)×(13x)
now,
x^2=572/11×13
x^2=4
x=2
hope it help....
