Question

If the perimeter of a rectangular field is 222 m add its breadth is 39 m then its area and length

Answer 1

Answer:

Length =?

Breadth = 39m

PERIMETER= 222m

Area=?

To find length:

2(l+b)=222

2(l+39)=222

l+39=222/2

l+39= 111

l= 111-39

l= 72m

Area= length × breadth

72×39

2808m²

Therefore, Length =72m and Area = 2808m²

Hope it helps!!

Answer 2

Step-by-step explanation:

Let the length of rectangular field be x m

The breadth of rectangular field = 39 m

Perimeter of rectangular field = 222 m

Therefore,

Perimeter of rectangle = 2(length+breadth)

222 = 2(x+39)

222 = 2x+72

222-72 = 2x

150 = 2x

150/2 = x

75 = x

x = 75

Length of the rectangular field = x = 75 m

Area of rectangle = length×breadth = 75×39 = 2925 sq. m.
