tell me the solution of this question​

Answer 1

Answer:

option 1) 40

Step-by-step explanation:

PSQT is a rectangle so,

the value of QT is 2cm and value of ST= 8cm (since opposite sides are equal)

STR is a triangle,so by applying Pythagoras theorem,

we get,

SR^2=ST^2+TR^2

10^2=8^2+TR^2

100-64=TR^2

36=TR^2

TR=6cm

so length of QR=Length of QT+TR

=2+6

=8cm

Area of quadrilateral PQRS=

1/2(sum of parallel sides) *height

=1/2(8+2)*8

=5*8

=40cm^2
