Answer 2

Answer :

• Length of rectangle is 7cm

Given :

• Area of rectangle park is 420cm²
• Breadth is 60cm

To find :

• Length of rectangle

Solution :

• Let the length of rectangle be l

As we know that,

• Area of rectangle = length × breadth

》 l × 60 = 420

》l = 420/60

》l = 7cm

Hence , Length of rectangle is 7cm

Verification :

As we know that,

• Area of rectangle = length × breadth

》60 × 7

》420

More Explanation :

• Perimeter of rectangle = 2(l + b)
