2x-7y=18 _(1)
-2x+4y=5
11y=23 , Y=23/11 sub in 1
2x-7×23/11=18
2x = 18×11 + 7×23
x = ( 198 + 161 )/2 = 359/2

Answer:
22,203 ft^2
Step-by-step explanation:
The area of a triangle with angle ∅ and two sides a and b is;
Area A = 1/2 × absin∅ ......1
The park is in the shape of a triangle, with two sides and an angle given;
Given;
a = 190 ft
b = 235 ft
∅ = 84°
Substituting the values into equation 1;
Area of the park;
A = 1/2 × 190 × 235 × sin84°
A = 22,202.70131409 ft^2
A = 22,203 ft^2 (to the nearest whole number)
Area of the park is 22,203 ft^2
Answer:
C = 2 * π * R = 2 * π * 14 = <u>87.9646 cm</u>
Step-by-step explanation:
All this means is that the perimeter, or circumference, is the distance or length around a shape or object. And the area is the amount of space inside the thing.
In today’s geometry lesson, you will review the formulas for finding the area and perimeter of basic geometric shapes.
