Step-by-step explanation:
Given the perimeter of the right-angle triangle is 60 m and the hypotenuse is 26 cm
Let the base and height of the right-angle triangle is a and b cm
Then a
2
+b
2
=(26)
2
∴a+b+
a
2
+b
2
=60⇒a+b+26=60⇒a+b=60−26⇒a+b=34
∴(a+b)
2
=(34)
2
⇒a
2
+b
2
+2ab=1156⇒2ab=1156−(26)

=1156−676=480⇒ab=240
Then area of right angle triangle =
