Question

the area of right angle triangle is 6 centimetre square if its base measures 4 cm and its a hypotenuse measures 5 cm find its perimeter

Answer 1

Base is 4cm and hypotenuse is 5cm. By Pythagoras theorem, 5*5=4*4+unknown side *unknown side. 25=16+p*p=>p*p=9=>p=√9=3. Perimeter =5+4+3=12cm

Answer 2

Area=1/2 b*h
b=4 cm
Area= 6
6= 1/2*4*h
6=2h
h=3

Therefore, perimeter=sum of all sides
= 4+5+3
=12
