Hi ,
Dimensions of the right angled
Triangle are ,
base = ( b ) = 5 cm
Hypotenuse ( h ) = 13 cm
Let Altitude = x cm
Perimeter of the triangle = 30cm
b + h + x = 30
5 + 13 + x = 30
18 + x = 30
x = 30 - 18
x = 12 cm
Area of the triangle = ( base × altitude)/2
= ( bx) /2
= ( 5 × 12 )/2
= 5 × 6
= 30 cm²
I hope this helps you.
