What Is The Perimeter Of A Right Triangle With Side Of 9 And 12?

According to the Pythagoras theorem the square of hypotenuse is equal to the sum of squares of base and perpendicular.

Hypotenues² = base² + perpendicular²

H² = B² + P²

Consider;

Base = 9

Perpendicular = 12

Then hypotenuse is ;

H² = 9² + 12²

H² = 81 + 144

H² = 225

H = 15

The perimeter of a right angle triangle is equal to the sum of measure of hypotenuse, perpendicular and base.

Perimeter of right angle triangle= hypotenuse + base + perpendicular

Perimeter of right angle triangle= 15 + 9 + 12

Perimeter of right angle triangle= 36
