Question

dimension of the plot is 20 cm x 15 cm. Find the length of the wire needed to fence the plot​? Answer the question

Answer 1

Answer:

70cm

Step-by-step explanation:

length = 20cm

breadth = 15cm

length of the wire needed to fence the plot = perimeter of rectangle

perimeter of rectangle = 2 × ( l + b )

perimeter of rectangle = 2 × ( 20 + 15 )

perimeter of rectangle = 2 × ( 35 )

perimeter of rectangle = 70cm

=> length of the wire needed to fence the plot = 70cm

Answer 2

Given :-

• Length of Plot = 20cm
• Breadth of Plot = 15cm

To Find :-

• The length of the wire needed to fence the plot.

Solution :-

❏ As we know that, Fencing is done on the boundary, so we have to find the Perimeter of the plot . Perimeter of Plot = length of the wire needed to fence the plot.

➞ Perimeter of Plot = 2( L + B )

➞ Perimeter of Plot = 2( 20 + 15 )

➞ Perimeter of Plot = 2 × 35

➞ Perimeter of Plot = 70cm

Thus 70cm of wire is needed to fence the plot.

Formulas Related to Rectangle :

• Perimeter of Rectangle = 2( l + b)
• Area = Length × Breadth
• Length = Area / Breadth
• Breadth = Area / Length
• Diagonal = √(l)² + (b)²
