Question

a field is in the form of a right triangle with hypotenus 50 m and one side 40 m. find the area of field

Answer 1

according to Pythagoras theorem

$50 ^{2} = 40^{2} + x ^{2}$
$x ^{2} = 250 - 160$
$x = 30$
area of field
$1 \div 2 \times b \times h$

$1 \div 2 \times 30 \times 40$
area of field=
$60 m^{2}$
