The area of this triangle is 60 cm2. The two legs are 13 cm and the base 24 cm (although you can use any unit you want).
Calculate the height of this triangle with the Pythagorean theorem:
h = √[ a2 − (b/2)2 ]
= √[ (13)2 − (24/2)2 ]
= 5 cm
Calculate the area of this triangle with the standard formula:
A = ½ × h × b
= ½ × 24 × 5
= 60 cm2
