Answer:
Length = 14cm
Breadth ( AKA Width) = 9cm
Explanation:
1) Address the facts
(L)Length = b + 5
(W)Width = b
(P)Perimeter = 46cm
= 2(b + 5 +b)
= 2(2b + 5) 2)Simplify the equation
3) Make b the SOTF (subject of the formula)
46 = 2(2b + 5)
46 = 4b + 10 3a) Simplify further
36 = 4b 3b) Minus 10 on both sides
9 = b
\____ 3c) Divide by 4 on both sides to get JUST b
4) Substitute aka replace the letters with numbers
L = b + 5
= 9 + 5
= 14cm
W = b = 9cm
Therefore the breadth(/width) is 9cm and the length is 14cm :)
