Give the example in step by step.​

Answer 1

Answer:

108 cm^2 is right answer sir ji THANK YOU SO MUCH

have a good life

Answer 2

Answer:

62

Step-by-step explanation:

length = 12 cm

diagonal = 15 cm

When we make a diagonal in a reactangle than it forms 2 right angled triangle,, so by Pythagoras thm.

base square = hypotenuse square - perpendicular square

So, ATQ

b = base of one of the right angled trianlge and also the breadth of reactangle

b= (15)*2 - (12)*2

b= 225-144

b=

$\sqrt{81}$

= 9 cm

Area of reactangle = l× b

So, 12×9= 108cm2
