Answer:
A = 120 cm²
Step-by-step explanation:
The 4 part of the ratio relates to the height of triangle A , then
16 ÷ 4 = 4 cm ← value of 1 part of the ratio, then
5 parts = 5 × 4 cm = 20 cm
The area (A) of triangle B is calculated as
A = 
bh ( b is the base and h the height )
Here b = 12 and h = 20 , then
A = × 12 × 20 = 6 × 20 = 120 cm²
Answer:
Step-by-step explanation:
