Question

Find the area of
the given polygon
ABCDEFGHIJ.
Given, AD = 7 cm,
Al = 6 cm, RE = JP =
4 cm,
BQ = SG = 3 cm,
BC = HG = 5 cm.​

Answer 1

Answer:

102cm2

Step-by-step explanation:

Area of ABCDEFGHIJ = Area of trapezium + area

of trapezium + area of

triangle + area of triangle

+ area of rectangle

Area of ABCDEFGHIJ = 2(Area of trapezium) +

= 2( Area of triangle ) + Area

of rectangle

Area of trapezium = 1/2×h(a+b)

= 1/2×3(5+7)

= 1/2×36

=18cm2

Area of triangle = 1/2×b×h

= 1/2×6×4

= 1/2×24

= 12cm²

Area of rectangle = l×b

= 6×7

= 42cm²

Area of ABCDEFGHIJ = 2(18)+2(12)+42

= 36+24+42

= 102 cm²
