Question

find the area of polygon ​

Answer 1

Answer:

57cm^2

Step-by-step explanation:

in triangle pqr

h=5cm

base=10cm

area= 1/2*b*h

=1/2*5*10

=25cm^2

in trapezium prst

two parallel sides are 10cm and 6cm

h=4cm

area=1/2*sum of parallel sides*height

=1/2*(10+6)*4

=1/2*16*4

=32cm^2

total Area=25+32

=57cm^2

Answer 2

Answer:

Area of polygon

1) Trapezium=h/2(a+b) = 4/2(10+6)

= 2x16 = 32

2 ) triangle = bh/2 = 10x5/2 = 25

(1) +(2) = 32+25=57cm2

Area of polygon=57cm2
