Question

In ∆PQR , PR = 8 cm, QR = 4 cm and PL= 5 cm , find
(a) the area of the∆PQR
(b) LM​

Answer 1

$\huge \fbox \red{Answer}$

a) QR = 4cm

PL = 5cm

Area of ∆PQR = 1/2 × b × h

= 1/2 × 4 × 5

= 10cm²

Answer 2

$\huge\pink{\boxed{\red{\textsf {\textbf{So}\blue{\textbf {\textsf{lu}}\pink{\textbf{\textsf{ti}}}\orange{\textsf{\textbf{on :-}}}}}}}}$

QR = 4cm

PL = 5cm

Area of ∆PQR = 1/2 × b × h

= 1/2 × 4 × 5

= 10cm²
