Answer 1

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.
