Q11 A field in the form of a parallelogram has one diaognal of 42m long and the perendicular distance of the diagonal from either of the outlying vertices is 10m find the area of the field ?

Answer 1

area of parallelogram = area of 2 triangle

area = 420 sq m

$= 2( \frac{1}{2} \times 42 \times 10) \\ = 42 \times 10 \\ = 420 \: {m}^{2}$
