Question

find the area of given triangle.If ps=2cm and QR
=4cm​

Answer 1

8 cm is the answer ???????

Answer 2

Given:

If PS = 2cm and QR = 4cm​

To find:

The area of the given triangle

Solution:

We know,

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

Let's consider

PQR is the triangle

PS is the perpendicular height on the side QR

Height = PS = 2 cm

Base = QR = 4 cm

Therefore,

The area of the triangle PQR is,

= $\frac{1}{2} \times QR \times PS$

= $\frac{1}{2} \times 4 \times 2$

= $\bold{4\:cm^2}$

Thus, the area of the given Δ PQR is → 4 cm².
