Question

If P = perimeter of a rectangle, l= it's length and b = breadth; find :
i) P, if l= 38 and b = 27 cm
ii) b, if P = 88 cm and l = 24
iii) l, if P = 96 m and b =28 m

Answer 1

p=2(38+27)=130 cm
b=P/2-l
=88/2-24
=20 cm
l=96/2-38=10 cm

Answer 2

i) if p=????
l =38
b=27
then perimeter of the rectangle=2(l+b)
=2(38+27)
=2(65)
=130cm---@ns.
ii) b=p/2-l
b=88/2-24
b=44-24
b=20----@ns..
iii) l=p/2-b
l=96/2-28
l=48-28
l=20----@ns...
