=>perimeter of right triangle is 40 cm
=>hypotenuse measure 17 cm
=>then , base + height = b+ h = 40 - 17 = 23
now , b² + h² = (17)²= 289
=>(b+h)²=b² + h²+ 2bh
=>(23)²= 289 + 2bh
=>2bh=529-289=240
=>bh=120
area = 1/2bh
area =1/2×120 = 60cm²
=>hypotenuse measure 17 cm
=>then , base + height = b+ h = 40 - 17 = 23
now , b² + h² = (17)²= 289
=>(b+h)²=b² + h²+ 2bh
