Multiply 12 and 5 which is 60, then multiply 8 and 3 which is 24. Subtract 24 from 60 to find the shaded area which is 36, so the shaded area equals 36 cm.
Multiply 36, 28, 11, and 22. Which equals 243,946 m. Then multiply 7, 6, 18, and 13 which equals 9,828 m. Then subtract 9,828 from 243,936 which equals 234,108
Answer:
A = 57.97 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = 
h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 6.2, a = 10.8 and b = 7.9, thus
A = × 6.2 × (10.8 + 7.9) = 3.1 × 18.7 = 57.97 cm²
