Help me ✏✔✔✔✔​

Answer 1

Answer:

80 m

Step-by-step explanation:

As we know perimeter of a rectrianle is 2(l+b)

so length = 120m

let breath be =x

So,

2(120+x) = 400

(120+x). = 200

x = 80m

Answer 2

Given :-

Perimeter of rectangular farm = 400m

Length of rectangular farm = 120m

To Find :-

Breath of rectangular farm = ?

Let the breath of rectangular farm be x

Solution :-

As we know that ,

Area of rectangle

= 2( Length +Breath )

Here , Length = 120 m , Breath = x m ,

Perimeter = 400m

Put the required values ,

400 = 2( 120 + x )

400/2 = 120 + x

200 = 120 + x

x = 200 - 120

x = 80m

Hence ,

The breath of the rectangle

= 80m$.$

Related formulas:-

• Area of rectangle = Length * Breath

• Perimeter of square = 4 * side

• Area of square = side * side

• Perineter of triangle = 3 * side

• Area of triangle = 1/2 * Base * height
