Question

The perimeter of rectangle is 24m and the area is 27m square. find the length and breath of the rectangle???

Who tell this answer correct I will mark as brainlist.

Answer 1

P=2 (l+b)
24/2=l+b
12=l+b----------(1.)

A=l×b
27=l x b - - - - - - - - - - (2.)

Now from equation 1 and 2

B=12-l - - - - - - - - - - - (3.)
& also, b=27/l
So,
27= l x (12-l)
27=l x 12 - l
27-12=2l
15=2 l
15/2=l
7.5=l
Now substituting the value of l in equation 3:
B=12-7.5
B=5.5

Therefore, l = 7.5
B=5.5
