Question

Please help me with this math problem ​

Answer 1

Answer:

$length = 15 \: cm \: \: and \: \: \: breadth = 7 \: cm.$

Step-by-step explanation:

$2(x + y) = 44 \\ \\ x + y = 22 \\ \\ y = 22 - x \\ \\ \\ xy = 105 \\ \\ x(22 - x) = 105 \\ \\ - {x}^{2} + 22x - 105 = 0 \\ \\ {x}^{2} - 22x + 105 = 0 \\ \\ {x}^{2} - 15x - 7x + 105 = 0 \\ \\ x(x - 15) - 7(x - 15) = 0 \\ \\ (x - 15)(x - 7) = 0 \\ \\ x =7 \: \: \: \: or \: \: \: \: x = 15 \\ \\ \\ y = 22 - 15 = 7 \: \: \: or \: \: \: \: y = 22 - 7 = 15 \\ \\ \\ \\ therefore \: \: \: length = 15 \: cm \: \: and \: \: \: breadth = 7 \: cm.$

Answer 2

Step-by-step explanation:

perimeter =2(length+breath)

44 = 2( L+B)

22 = L+B

22 = 1+ 21

it means 21cm breath
