Question

the are of the shaded part is 112cm^2. find the value of x​

Answer 1

Answer:

$The \: area \: of \: shaded \: part =112cm² \\ </p><p>The \: length \: of \: rectangle \: = 12cm \\ </p><p>The \: breadth \: of \: rectangle \: = 11cm \\ </p><p>The \: area \: of \: rectangle \: =l \times b \\ </p><p>= 11cm \times 12cm \\ </p><p>=132cm² \\ </p><p>x²= \: The \: area \: of \: rectangle - The \: area \: of \: shaded \: part</p><p> \\ x²=(132-112)cm²</p><p> \\ x²=20 {cm}^{2} \\ \sqrt{x \times x }= \sqrt{2 \times 2 \times 5 } \\ x = 2 \sqrt{5} \\ x = 2 \times 2.24 \\ x = 4.47 \\ The \: length \: of \: rectangle \: = (12 - 4.47 )cm \\ = 7.53cm \\ The \: breadth \: of \: rectangle \: = (11 - 4.47 )cm \\ = 6.53cm$
