Question

The perimeter of a rectangular field is 151m .if it's breath is 32m,find it's length and area

Answer 1

Hello!!!

__________________________________________

Given:-

Perimeter of rectangle= 151m.
breadth= 32m

To find:- Length & Area.

Let the length of rectangular field be , 'x'.

And as we already know,

Perimeter of rectangle= 2 ( L +B).

151 = 2( 32+ x)
75.5 = 32 + x.

or, 32 + x= 75.5.
so, x= 75.5 - 32

Therefore= 43. 5.

So, Length of rectangle will be 43.5 m.

____________________________________

Now, Area of rectangle= Length × Breadth
So , Area of rectangle= 43.5× 32 = 1,392m^2.
