Question

A rectangular field has length = 20cm
and diagonal = 25 cm.
Find the area of the field.​

Answer 1

Answer:

$using \: pyhtgores \: therom$

${25 }^{2} = {20}^{2} + {breadth}^{2}$

$625 = 400 + {breadth}^{2}$

${breadth}^{2} = 625 - 400$

${breadth}^{2} = 225$

$breadth = 15cm$

$area \: of \: rectangle \: = length \times breadth$

$area = 20 \times 15$

[tex]the \: area \: of \: field \: is \: 300[/tex]
