Question

Find the breadth of a rectangle whose perimeter is 146m and length is

34.5 m​

Answer 1

Answer:

38.5m

Step-by-step explanation:

Let breath be b

Perimeter=2(l+b)

146= 2(34.5+b)

146=69+2b

2b=146-69

2b=77

b=77/2

b=38.5

Breath =38.5m

Answer 2

Answer:

rectangle peri = l × b

= 34.5 × b = 146

b = 146÷34.5

breath = 4.23 m
