Question

एक समद्विबाहु समकोण त्रिभुज का क्षेत्रफल 200 cm2 है तो इसके कर्ण की लम्बाई ज्ञात करें ।
​

Answer 1

Let the sides be b.
So area of triangle
1/2 x b x b = 200
b x b = 400
So b = 20 cm

Now hypotenuse^2 = b^2 + b^2
= 20^2 + 20^2
= 400 + 400
= 800
So hypotenuse = sqrt(800) = 20 sqrt(2)

sqrt means sqaure root
