perimeter 12
sum of other two sides other than hypotenuse is 12 - 5 = 7 3 + 4 = 7 according to the triplet Pythagoras Theorem 345 area will be equal to 6 CM square this can be calculated using heron's formula hope this helps you!!!

let triangle be ABC
perimeter of ABC = 12
AB + BC + CA = 12
Let the two sides of the triangle be x and y.
x + y + 5 = 12 _________(1)
x^2 +y^2 = 5^2 _________(2)
y = 7 - x _________ (3)
Substituting:(3) in (2)
x^2 + (7 - x)^2 = 25
x^2 + 49 - 14x + x^2 = 25
2x^2 - 14x + 24 = 0
2(x^2 - 7x + 12) = 0
2(x - 3)(x - 4) = 0
x = 3 and 4
The two sides measure 3 and 4cm.
The area is given by A = (B x H)/2 where B and H are the two sides .
A = (3 x 4)/2
A = 6 square centimetres.
In summary:
The triangle has sides of 3, 4 and 5 centimetres. The area is of12" cm"^2
