Perpendicularh=12cmBaseb=16cmHypoteneousl=20cm

02

Step 2. Formula used.

PerimeterofrightangletriangleP=h+b+lAreaofrightangletriangleA=12bh

03

Step 3. Calculate the perimeter of right-angle triangle.

PerimeterofrightangletriangleP=h+b+lP=12+16+20P=48cm

04

Step 4. Calculate the area of right-angle triangle.

AreaofrightangletriangleA=12bhA=121612A=96cm2

Therefore,

PerimeterP=48cmAreaA=96cm2
