Answer:
Length is 30cm
Width is 13cm
Step-by-step explanation:
Let the width be x cm;
The length will be 2x + 4 cm
Perimeter = 86cm
Perimeter is given by (2 × length) + (2 × width)
2(2x + 4) + 2x = 86cm
4x + 8 + 2x = 86cm
6x = 86 - 8 = 78cm
x = 78/6 = 13cm
Width (x) = 13cm
Length = 2(13) + 4 = 26 + 4 = 30cm

Answer:
4%/ a interest compounded semi-annually
Step-by-step explanation:
The option that gives the lower interest rate payment would be more appropriate. to determine this calculate the effective interest rate
Effective annual rate = (1 + APR / m ) ^m - 1
M = number of compounding
(1 + 0.04/2)^2 - 1 = 4.04%
(1 + 0.04/12)^12 - 1 = 4.07%
the choice should be 4%/ a interest compounded semi-annually
