Question

Find the breadth of a rectangle of perimeter 660 m and whose length is 210m. 19)​

Answer 1

Answer:

breadth = 120m

Step-by-step explanation:

perimeter og rectangle = 2(l+b)

660=2(210+b)

660=420+2b

660-420=2b

2b= 240

b=240/2

b=120m

Answer 2

Answer:

I THINK THE ANSWER SHOULD BE 239.62

Step-by-step explanation:

P= 2(L+B)

660=420.38 +b

B= 660-420.38

B= 239.62

To CHECK= we can use the formula I. e, 2(l+b)= 660= 2 (210.19+239.62)

660= 660
