Question

find the area of a triangle whose base is 15 cm and the corresponding height is 9.8 cm

Answer 1

Answer:

73.5 cm²

Step-by-step explanation:

Area of a triangle = 1/2  × b  × h

= 1/2  × 15  × 9.8

= 73.5 cm²

Answer 2

Given

Base of a triangle is $15cm$

Height of a triangle is $9.8cm$

We have to find the area of a triangle

We know that,

If base and height are given

Formula,

Area of a triangle $= \frac{1}{2}\times$base$\times$height

Substitute the given values in the above formula, we get

Area $= \frac{1}{2}\times15\times9.8$

$= 1\times15\times4.9$

$= 73.5$

Therefore, the area of a triangle is $73.5cm^{2}$.
