Answer:
30 square.cm
Step-by-step explanation:
here, AB perpendicular AC
area of triangle = 1/2 × Base × height.
= 1/2 × AB × AC
= 1/2 × 5 × 12
Area of the triangle = 30 sq.cm
AB square + AC square = BC square. (5)square + (12)square = BC square.
25 + 144 = BC square
169 = BC square
BC = 13 cm.
Now, AD is height and BC is Base.
area of triangle = 30
1/2 × AD × BC =30
1/2 × AD × 13 =30
AD = 60/13.
