Question

thearea of right triangular board is 422.86msquare. if of the side containing right angle is 42.2m, then find the other side​

Answer 1

Answer:

Area is square = Side × Side

≈ 422.86 = 42.2 × X

≈ 422.86 ÷ 42.2 = X

≈ 10.0203 = x

Answer 2

Answer:

$area \: of \: right \: \triangle = \frac{1}{2} \times one \: side \times other \: side \\\\ \therefore 422.86 = \frac{1}{2} \times 42.2 \times other \: side \\ \\ \therefore \: other \: side = \frac{422.86 \times 2}{42.2} \\\\ \therefore \: other \: side = \frac{845.72}{42.2} \\ \\\therefore \: other \: side = 20.04 \: m$
