Answer:
Base of the triangle will be 12.5cm
Explanation:
We know that,
➠ Area of a traingle is : ½ · base · height
- height = 16cm.
- Area = 100cm²
So,
➠ 100 = ½ · base · 16
➠ 100 = 8 · base
➠ 100/8 = base
➠ 12.5 = base
Base of the traingle is 12.5 cm
Quick check :
Calculate the area again :
- We should the area as 100cm²
Area of a traingle = ½ · base · height
- base is 12.5cm
So,
Area of the triangle :
➠ ½ · 12.5 · 16
➠ 12.5 · 8
➠ 100
Hence, proved ✔
