Hii dear here is your answer

This answer is verified ✅✅

Perimeter of rectangle = 2(l+b)

Given,
Perimeter = 75 m
length,l = 20m
breadth, b = ?

Put in formula........

75 = 2(20+b)

75/2 = 20+b

37.5 = 20+b
37.5 - 20 = b
b = 17.5m

Answer 2

Hi,

Answer: 17.5m

Step-by-step explanation:

Perimeter of  the rectangle = 75m

                            i.e, 2(l + b) = 75m

                              2(20 + b) = 75m

                                    20 + b = 75/2 = 37.5

Therefore, b = 37.5 - 20 = 17.5m  

Hope this helps you :)
