Answer 1

Sorry I don’t know the answer

Answer 2

The length and breadth of the rectangle is 57 m and 38 m respectively.

Explanation:

It is given that,

A rectangular ground is surrounded by 190 m long wire, perimeter of the rectangle is 190 m.

Let l and b are the length and breadth of the rectangle such that,

$l=1\dfrac{1}{2}\times b=1.5b$

The perimeter of a rectangle is given by :

$P=2(l+b)$

$190=2(1.5b+b)$

$190=5b$

b = 38 m

Length of the rectangle,

$l=1.5\times 38$

l = 57 m

So, the length and breadth of the rectangle is 57 m and 38 m respectively. Hence, this is the required solution.
