Question

the area of right triangle is 84cm if one of its leg is 24cm long find length of other 2 sides of triangle

Answer 1

${\huge {\mathfrak {Answer :-}}}$

Let another leg be x.

So, 1/2 * 24 * x = 84

Or, x = 84/12 = 7.

And hypotenuse

= (24^2 + 7^2)^1/2

= (476 + 49)^1/2

= (625)^1/2

= 25.

➡️ $<b>The other two sides are 7 cm and 25 cm. </b>$

That's it..

Answer 2

Answer:

Step-by-step explanation:

Let ABC be the right triangle

BC =24 cm & area of triangle = 84 cm^2

Area of triangle = 1/2× AB × BC

84 = 1/2× AB × 24

84 = 12 × AB

84/12 = AB

7 = AB

By Pythagoras theorem

AC^2 = AB^2 + BC^2

= ( 7)^2 + (24)^2

= 49 + 576

= 625

AC = 25

* lengths of other two sides of right

triangle is 25 cm & 7 cm.
