Answer:
160 m²
384 m²
Step-by-step explanation:
The area of a trapezium is given by :
A = 1/2(a + b)h
h = height ; a and b = lengths
From the diagram :
A = 1/2(12 + 20)10
A = 1/2(32)10
A = 16 * 10
A = 160 m²
2.)
Area of parallelogram = base * height
Base = 24 ; h = 16
A = 24 * 16
A = 384 m²
70: 1,2,5,7,10,14,35,<span>70
20: 1,2,4,5,10,20</span>
Step-by-step explanation:
okay so -25 • -9 = 9+10
225 = 9+10
225 = 19
19. 19
= 11.8
