Question

the ratio of length to the breadth of a rectangle is 7:4. if the perimeter is 220m
find the length of the tectangle



​

Answer 1

$According \: to \: Question \\ \\ 2(l + b) = 220 \\ \\ 2(7x + 4x) = 220 \\ \\ 2(11x) = 220 \\ \\ 22x = 220 \\ \\ x = \frac{220}{20} \\ \\ x = 11 \\ \\ \\ So \: Length = 7x \\ \\ = 7 \times 11 \\ \\ = 77 \\ \\ \\ So \: Breadth = 4x \\ \\ 4 \times 11 \\ \\ = 44$
