Answer:
7cm
Step-by-step explanation:
Area = Length x width
A = 35
w= L - 2
L = w+ 2
Now it becomes
35 = ( w+2) x w
35 = w^2 + 2w
W^2 + 2w - 35 = 0
By Factorization we have
( w + 7)( w-5)
w = 5cm
Since L = w + 2, we have
L = 5 + 2
= 7cm
Answer:
x = 20
Step-by-step explanation:
(2 + 3x) and 62° are vertically opposite angles and are congruent, so
3x + 2 = 62 ( subtract 2 from both sides )
3x = 60 ( divide both sides by 3 )
x = 20
