Answer:
6cm2.
Step-by-step explanation:
The sides of a right-angled triangle are equal three consecutive numbers.
Now, (AC)2 = (AB)2 + (BC)2
=) (m+2)2 = m2 + (m+1)2
=) m2 + 4m + 4 = m2 + m2 + 2m + 1
=) m2 − 3m + m − 3 = 0
=) m(m−3) + 1(m−3) = 0
=) (m+1)(m-3)=0
=) m=3 [Where m ≠ 1].
Therefore, Area of triangle = 12 x (m+1) x m
= (12 x4 x 3)cm
= 6cm2.
