Step-by-step explanation:
perimeter of rectangle is 44 cm
area of rectangle is 117 cm^2
formula of perimeter of rectangle is
2(l+w)= 44
l+w= 44/2
l+w= 22
l=22-w
formula of area of rectangle is
w*l=117
w*(22-w)=117
22w-w^2=117
w^2-22w+117=0
w^2-13w-9w+117=0
w(w-13)-9(w-13)= 0
(w-13)(w-9)= 0
so, w= 13cm or 9cm
we choose w=9cm because width can't be greater than length.
if w= 9cm then l=13cm
a) if one side of rectangle is taken as 11+X
(11+13)=24cm then the other side must be 24 cm
because the opposite side of rectangle is equal.
b) length of rectangle is 13 cm and width of rectangle is 9 cm
