Answer:
Step-by-step explanation:
as if we form an imaginary triangle with this line as hypotenuse
we get
- base = 3 units
- perpendicular = 4 units
using Pythagoras theorem:-
hyponteuse ² = perpendicular ² + base²
hyp² = 4² + 3²
hyp² = 16 + 9
hyp = 5 units
Perimeter
2l + 2w = 27
l + w = 13.5
Area
l*w = 35
(35 / l) + l = 13.5
35 + l^2 = 13.5l
l^2 - 13.5l + 35 = 0
Using this equation, we can find the length first
then width can be found
