Answer:
Area : 30cm^2 and the length of ab : 13cm
Step-by-step explanation:
We have a right angled triangle
where,BC is perpendicular and length is 5cm and CA which is the base is 12cm.
Area= 1/2 × base × height
= 1/2 × 12cm × 5cm
= 30cm^2
By a Pythagoras theorem
BC is perpendicular = 5 cm
CA is the base = 12cm
BA is hypotenous = ?
Hypotenous = √ base^2 + perpendicular^2
? = √(12cm)^2 +( 5cm)^2
= √ 144cm^2 + 25cm^2
=√169cm^2
= 13cm
