Answer» Given Lenght of RECTANGULAR field is 20 m more than it's breadth Perimeter of the field is 280 m ________________________________ To Find The LENGTH ________________________________ Solution Let the breadth be 'x'. Lenght = x + 20 Formula to find Perimeter of Rectangle → 2 × (Lenght + Breadth) Perimeter of Rectangular Field → 280 m Let's solve the below equation to find the length and breadth of the rectangular field. 2 (x + 20 + x) = 280 Step 1: Simplify the equation. ⇒ 2 (x + 20 + x) = 280 ⇒ 2 (x + x + 20) = 280 ⇒ 2 (2x + 20) = 280 ⇒ 4X + 40 = 280 Step 2: Subtract 40 from both sides of the equation. ⇒ 4x + 40 - 40 = 280 - 40 ⇒ 4x = 240 Step 3: Divide 4 from both sides of the equation. ⇒ 4x ÷ 4 = 240 ÷ 4 ⇒ x = 60 ∴ Breadth → x = 60 m ∴ Length → x + 20 = 60 + 20 = 80 m ∴ The length of the given rectangular field is 80 m. ________________________________

Let the breadth be 'x'.

Lenght = x + 20

Formula to find Perimeter of Rectangle → 2 × (Lenght + Breadth)

Perimeter of Rectangular Field → 280 m

Let's solve the below equation to find the length and breadth of the rectangular field.

2 (x + 20 + x) = 280

Step 1: Simplify the equation.

⇒ 2 (x + 20 + x) = 280

⇒ 2 (x + x + 20) = 280

⇒ 2 (2x + 20) = 280

⇒ 4X + 40 = 280

Step 2: Subtract 40 from both sides of the equation.

⇒ 4x + 40 - 40 = 280 - 40

⇒ 4x = 240

Step 3: Divide 4 from both sides of the equation.

⇒ 4x ÷ 4 = 240 ÷ 4

⇒ x = 60

∴ Breadth → x = 60 m

∴ Length → x + 20 = 60 + 20 = 80 m

∴ The length of the given rectangular field is 80 m.
