B. 84 m²

Step-by-step explanation:

If you view it as a triangle rotated to the left, it would have a base of 8+8=16 and a height of 12, so its area would be 16*12/2 = 96 m². But a piece is missing. What is missing is a little triangle with base 4 and height 6 and area 4*6/2 = 12.

So the resulting area is 96-12 = 84 m²

B

Step-by-step explanation:

The figure is composed of a right triangle and a trapezium.

area of Δ = × 12 × 8 = 6 × 8 = 48 m²

area of trapezium = h (a + b)

where h is the height and a, b the parallel bases

Here h = 4, a = 6 and b = 12, thus

area = × 4 × (6 + 12) = 2 × 18 = 36 m²

Total area = 48 + 36 = 84 m² → B

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

multiply
