Question

The area of a rhombus is 98m².If one of its diagonal is 14 m,find the

other diagonal.​

Answer 1

$area \: \: of \: \: rhombus = \frac{1}{2} \times d1 × d2. \\ 98 = \frac{1}{2} \times 14 \times d2\ \\ \\ 98 \times 2 = 14 \: d2 \\ \\ \frac{196}{14} = d2 \\ \\ 14 = x$

Answer 2

Answer:

$as \: we \: know \: the \: rhombus \: area \: \\ \frac{1}{2} \times a \times b \: \\ a = 14 m \\ area \: = 96m ^{2} \\ we \: write \: it \: as \: \\ area \: = \frac{1}{2} a \times b \\ put \: \\ the \: value \\ 96m^{2} = \frac{1}{2} \times 14m \times b \\ 96m ^{2} = 7m \times b \\ 96m ^{2} \div 7m \: = b \\ 14 = b$
