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 )
Therefore, the combined area of the two plots of land = 2400 + 2400
= 4800 square yards
Answer: C. OmZWXY + m ZYXZ = 180
c) 3x - 45 = 10
Cross multiply,
3*(x - 15) = 2*5
3*x - 3*15 = 10
3x - 45 = 10
