Question

- The length of hypotenuse of a right angled triangle is 13 and the length of another side is 5 cm. Find its area.​

Answer 1

Answer:

30cm²

Step-by-step explanation:

length of hypotenuse = h = 13cm

length of a side = a = 5cm

let length of the other side = xcm

now using pythagoras theorem, we get

x² + 5²  =  13²

x² + 25 =   169

       x²  =  169 - 25

       x²  =  144

        x   =  12cm

area of right angled triangle = 1/2 x (ab)

where a,b are sides making right angle

area of triangle = 5x12 ÷ 2

area of triangle = 30cm²

Answer 2

Answer:

30cm²

Step-by-step explanation:

a Leg

5

cm

c Hypotenuse

13

cm

Using the formulas

A=ab

2

c=a2+b2

Solving forA

A=1

2ac2﹣a2=1

2·5·132﹣52=30cm²
