Question

The perimeter of right angle triangle is 40 c if its hypotenuse is 17 cm find its area

Answer 1

P+b+h=40

P+b=27

Squaring both sides

P^2+b^2+2pb=729

( using pythagoras theorem)

289 +2pb=729

2pb=440

Pb=220

Therefore area=1/2pb=110 cm^2

Answer 2

Answer:

P+b+h=40

P+b=27

Squaring both sides

P^2+b^2+2pb=729

( using pythagoras theorem)

289 +2pb=729

2pb=440

Pb=220

Therefore area=1/2pb=110 cm^2
