Question

If Length and breadth of a rectangle are (x+5) units and (x-5) units respectively, then Perimeter of this
rectangle will be:
a) xsq-25) sq, units b) (2x+ 10) units
c) 4x + 20 units
d) (4x) units​

Answer 1

Answer:

Answer is

D) (4x) units

Step-by-step explanation:

length=(x+5), breadth=(x-5)

perimeter of rectangle

= 2(l+b)

= 2[(x+5) + (x-5)]

=2(x+5+x-5)... (different signs cancelation)

=2(2x)

=(4x) units.
