​

Answer 1

Answer:

PLS MARK THIS ANSWER AS BRAINLIEST ANSWER

Step-by-step explanation:

Option (c) is corrmt

Given that PL=8cm

PR=12cm

QR=6cm

Now, In right-angled triangle PLR

Using Pythagoras theorem,

⇒PR2=PL2+LR2

⇒LR2=144−64

⇒=80=45cm

LR=LQ+QR

⇒LQ=LR−QR=(45)cm

Now area of triangle PLR

A=21×(45)×8

=165cm2

Now, area of triangle PLQ

A=21×(45)×8

=(165−24)cm2

Hence, area of triangle PLR = Area on triangle PLQ + Area of triangle PQR

So, area of triangle PLR − Area on triangle PLQ = Area of triangle PQR

⇒165−(165−24),

⇒  Area of triangle PQR =24cm2
