Answer:
and 
Step-by-step explanation:
(a)
A =
× 4
× 
= 2
× 
=
×
← rationalise the denominator
=
units²
(b)
Using Pythagoras' identity in the right triangle
let hypotenuse be h , then
h² = (4
)² + (
)²
= 32 + 
=
+ 
=
( take the square root of both sides )
h =
=
×
← rationalise the denominator
h = 
= 3/5(x) + 3/5(x) + 2/5
= 6/5(x) + 2/5
= 2/5 (3x+1)
