Answer 1

Step-by-step explanation:

Area of CDEF "Rectangle" :- L x B

where L :- 5cm and B :- 28cm

so

Area :- ( 5 x 28 ) = 140cm²

.

.

now area of two equal Trapezium:-

.

.

Area of Trapezium :- (1/2)•(a+b)h

where:- a = 5cm ; b = 10cm ; h = (40-28) = 12cm

.

Area of Two equal Trapezium is:- 2x(1/2)•(a+b)•h

2x(1/2)•(a+b)•h

2x(1/2)•(5+10)•(12)

(15x12)

180 cm²

.

.

Totall Area of given figure:-

140 + 90 + 90

320cm²
