Step-by-step explanation:
This is how you would proceed:
Centered at D, draw an arc of 7m (3.5cm) within the garden (rectangle).
Centered at B, draw an arc of 4m (2cm) within the garden.
There will be two intersection points, one is outside the garden (that you will not see), and the other is within the garden, which is where the tree should be planted.
See illustration attached.
Answer:
The fraction will increase by 100%
Step-by-step explanation:
Say the fraction is x/y. The question is telling us to decrease x by 20% (i.e. 0.8x) and to decrease y by 60% (i.e. 0.4y):
You can see that by applying these changes, the new fraction is actually double the old fraction (i.e. will increase by 100%).
