 Given:-

  •  Diagonal \: \: of \: \: Rhombus \: \: = \: \: 90 \: m \: \: and \: \: 400 \: m.

 To \: \: Fine:-

  •  height
  •  perimeter

 Solutions:-

  •  formula \: \: of \: \: finding \: \: the \: \: side \: \: of \: \: rhombus \: \: when \: \: diagonal \: \: are \: \: given:-

 \: \: \: \: \: side \: \: = \: \: \frac{\sqrt{{(diagonal_1)}^{2} \: + \: {(diagonal_2)}^{2}}}{2}

 \: \: \: \: \: side \: \: = \: \: \frac{\sqrt{{90}^{2} \: + \: {400}^{2}}}{2}

 \: \: \: \: \: side \: \: = \: \: \frac{\sqrt{{8100} \: + \: {160000}}}{2}

 \: \: \: \: \: side \: \: = \: \: \frac{\sqrt{168100}}{2}

 \: \: \: \: \: side \: \: = \: \: \frac{410}{2}

 \: \: \: \: \: side \: \: = \: \: {205}

  •  Area \: \: of \: \: rhombus \: \: when \: \: diagonal \: \: are \: \: given;

 \: \: \: \: \: area \: \: = \: \: \frac{1}{2} \: × \: {d_1} \: × \: {d_2} \: \: \: Sq. \: \: units.

 \: \: \: \: \: area \: \: = \: \: \frac{1}{2} \: × \: {90} \: × \: {400}

 \: \: \: \: \: area \: \: = \: \: \frac{1}{2} \: × \: {36000}

 \: \: \: \: \: area \: \: = \: \: \frac{36000}{2}

 \: \: \: \: \: area \: \: = \: \: {18000} \: \: \: Sq. \: \: units.

 Area \: \: of \: \: Rhombus \: \: = \: \: {18000}

  •  \: \: \: \: \: base \: \: = \: \: 205 \: m

 \: \: \: \: \: b \: × \: h \: \: = \: \: 18000 \: m

 \: \: \: \: \: 205 \: × \: h \: \: = \: \: 18000 \: m

 \: \: \: \: \: h \: \: = \: \: \frac{18000}{205} \: m

 \: \: \: \: \: h \: \: = \: \: {87.8} \: m

 \: \: \: \: \: perimeter \: \: = \: \: 4 \: × {(side)}

 \: \: \: \: \: perimeter \: \: = \: \: 4 \: × {205}

 \: \: \: \: \: perimeter \: \: = \: \: {820} \: units.

So,

  1.  \: \: \: \: \: Reight \: \: of \: \: rhombus \: \: ⇢ \: \: {87.8} \: m.
  2.  \: \: \: \: \: Perimeter \: \: of \: \: rhombus \: \: ⇢ \: \: {820} \: m.
