The Area of the lawn is:
20m x 14m = 280m^2
The Area of the Circle is:
pi x 5^2 = 78.54
280 - 78.54 = 201.46m^2
let x = a number
difference means that its subtraction
twice a number is 2x
so the equation should be
2x-5=3
add 5 to both sides
2x=8
divide both sides by 2
x=4
Answer:
23.1m
Step-by-step explanation:
we define x to be the actual distance, y to be the distance on map (y=15.4cm)
if the map scale is 3:750, then by definition of scaling, x and y must satisfy:

we isolate x:
