Question

solve question 10 step by step​

Answer 1

let the breadth (b)=X metre

therefore the length(l)=(x+3)m

therefore according tho the problem...

$2(x + x + 3) = 30 \\ = > 2x + 3= 15\\ = > 2x = 12\\ = > x = 6$

therefore the length is =9 metre and the breadth is =6 metre

Answer 2

Answer:

given that length of rectangle is 3 m and breath of rectangle is 3m

sol_as we know parameter of rectangle is 2(l+B)

l=3m

B=3m

so __2(3+3)=

2(6)=12m answer
