Question

14. The perimeter of a square is 64 m. The area of a rectangle is 6 mº less than the area of the
given square. If the length of the rectangle is 25 m, then find its breadth.
​

Answer 1

Answer:

perimeter of a squre =4×side

64 =4×x

4x=64

x=64/4=16m

area of square=side×side

=16×16

=256

area of rectangle=256-6

=250

l×b=250

16×b=250

b=250÷16

15.6

Answer 2

Answer:

Perimeter of square= 4*side

64=4*side

64/4=side

16m= side

area of rectangle= area of square-6m

=(side)^2-6m

=(16)^2-6m

=256-6m

=250m^2

area of rectangle =length*breadth

250 =25*breadth

10m=bteadth
