Answer:

Step-by-step explanation:

3/(x-3) = 8/(2x+6)

or, 3(2x+6) = 8(x-3) ( by cross multiplication)

or, 6x + 18 = 8x - 24

or, 8x - 6x = 24 + 18

or, 2x = 42

or, x = 42/2

=21

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
