Answer:

(4, 5)

Step-by-step explanation:

5x + y = 25

-3x + 2y = -2

5x + y = 25

y = 25 - 5x

-3x + 2 * (25 - 5x) = -2

-3x + 50 - 10x = -2

-13x = -52

x = 4

5 * 4 + y = 25

20 + y = 25

y = 5

Solution: (4, 5)

A farmer has a rectangular plot of land. There is a bother identical plot of land 100 yards east and 100 yards north. Find the c

Anna [14]

Answer:

Step-by-step explanation:

Area of a rectangular plot = Length × width

With the aid of the diagram attached below.

<u>For plot 1:</u>

The area = ( 60 - 20 ) × ( 80 - 20 )

Area = 40 × 60

Area = 2400 sq yard

<u>For plot 2:</u>

Area = (160 - 120 ) × ( 180 - 120 )

Area = 40 × 60

Area = 2400 sq yard

Therefore, the combined area of the two plots of land = 2400 + 2400

= 4800 square yards
