Question

Length of rectangular field is 15 m and diognal is lenght 17m . Find its area and the perimeter.

Answer 1

$given \\ length \: = 15m \\ diagonal = 17m \\ \\ using \: pythagoras \: theorem \\ {h}^{2} = {b}^{2} + {p}^{2} \\ {17}^{2} = {15}^{2} + {p}^{2} \\ 289 = 225 + {p}^{2} \\ 289 - 225 = {p}^{2} \\ 64 = {p}^{2} \\ p = \sqrt{64} \\ p = 8m \\ \\ area \: = l \times b \\ area = 15 \times 8 \\ area = 120 {m}^{2}$
perimeter = 2 (l+b)
perimeter = 2( 15+8)
perimeter = 2*23 =46m²
