A farm covers land in the shape of a trapezium. The length of the northern boundary of the farm is 265 m and length of the south
igor_vitrenko [27]

Answer:

Step-by-step explanation:

Part A

<u>Givens</u>

b1 = 265

b2 = 180

h  = 90

<u>Formula</u>

Area = (b1 + b2)*h / 2

<u>Solution</u>

Area = (265 + 180) * 90 / 2

Area = 445 * 90 / 2

Area = 40050 / 2

Area = 20025 square meters

Part B

1 hectare = 10000 square meters

x hectare = 20025 square meters         Cross multiply

x * 10000 = 20025 * 1                             Divide by 10000

x  = 20025 / 10000

x = 2.0025

Rounded to the nearest hectare that would be 2

Part C

The best shape is a square.

That would mean that the area is given by

s^2 = 20025

sqrt(s^2) = sqrt(20025)

s = 141.51

Each side of the rectangle (square) = 141.51

What is the answer to 6x = 54
Morgarella [4.7K]

Answer:

It's division because to get x by itself, you need to divide both sides. X = 9

Step-by-step explanation:

6x = 54

Divide both sides by 6

54/6 = 9

Simplify 2 to the 5 power to the fourth power over 3 to the second power
melisa1 [442]
I'm assuming you mean 2^(5)(4/3)(2). 
So multiplying all of the powers together yields 2^(40/3)
