Question

Find the base of each of the following
triangles from the given data :
(1) Area = 100cm², h=16cm​

Answer 1

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 ✔
