Answer:
60 cm² and 36 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2} [/tex] bh ( b is the base and h the perpendicular height )
Here b = 10 and h = 12 , then
A = [tex]\frac{1}{2} [/tex] × 10 × 12 = 5 × 12 = 60 cm²
The perimeter (P) is the sum of the 3 sides
P = 13 + 13 + 10 = 36 cm
