Question

Find the base of triangle whose: Area = 300cm height = 7.5cm​

Answer 1

Given:-

• Height of triangle is 7.5 cm.
• Area of triangle is 300 cm².

To find:-

• Base of triangle.

Solution:-

We know that,

Area of triangle = 1/2 × base × Height

Height of triangle = 7.5 cm.

Area of triangle = 300 cm²

Put height and Area of triangle in formula,

⇒ 300 = 1/2 × base × 7.5

⇒ 300 × 2 = base × 7.5

⇒ 600 = base × 7.5

⇒ 600/7.5 = base

⇒ 80 = base

Or , Base = 80

Therefore,

Base of triangle is 80 cm.

Answer 2

answer: the answer is 80 cm
