Question

the perimeter of an a4 size paper sheet is 39.92 inches. if its length is 11.69 inches, find its breadth​

Answer 1

Answer:

$p = 2(l + b) \\ 9.82 = 2(11.69 + b) \\ \frac{9.82}{2} = 11.69 + b \\ 4.91 - 11.69 = b \\ - 6.78 inch= b$

I hope u help

Answer 2

Answer:

perimeter = 39.92 inches

2( length + breadth )= perimeter

2 (11.69 + breadth) = 39.92

11.69+ breadth =39.92 ÷2

11.69+ breadth = 19.96

breadth = 19.96 - 11.69

breadth =8.27 inches
