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

A rectangle has a side length of (x+2) meters and a width of (2x+3) meters.
Kaylis [27]

Step-by-step explanation:

area=length x width

91=(x+2)(2x+3)

91=x^2+5x+6

x^2+5x-85=0

x=14.2 orx=-24.1

The longest diagonal
Ratling [72]
The diagonals are:
diagonal₁=2x+3y
diagonal₂=(x+8)+(2y+5)
We have to solve the following system of equations:
2x=3y
(x+8)=(2y+5)
We solve this system by substitution method:
2x=3y  ⇒x=3y/2

(3y/2 +8)=2y+5
3y+16=4y+10
-y=-6
y=6

x=3y/2=3*6/2=9

we obtain the measure of the diagonals:
diagonal₁=2x+3y=2*9+3*6=18+18=36
diagonal₂=(x+8)+(2y+5)=(9+8)+(2*6+5)=17+17=34

Answer: The longest diagonal is 36 units.
