<h3>What is unitary method ?</h3>
Unitary method is a technique for first solving the value of a single digit unit and from there we can find the value of any given unit.
According to the given question lillian drew a scale drawing of a county park. the scale she used was 1 inch : 4 yards.
The picnic area is 80 yards wide in real life.
∴ The width of the picnic area in here drawing in inches will be
= 80/4 inches.

Answer:
Explanation:
<u>using the formula:</u>
Answer:
57, 57, 66
Step-by-step explanation:
This is isosceles, so angle B is the same measure as angle C, and all 3 angles add to 180.
2x+47 + 2x+47 + 3x+51 = 180
7x + 145 = 180
7x = 35
x = 5
Angles B and C are 2x + 47, so 2(5) + 47 = 57
Angle D is 3x+51, so 3(5) + 51 = 66
