Question

A field is in the shape of an quadrilateral ABCD in which side AB=18m, AD=24m, BC=40m, DC=50m and angle A=90°. Find the area of the triangle

Answer 1

which triangle? is it ABD?
if the triangle is ABD use the formula for calculating area of triangle which is
= 1/2x base x height
here angle A is 90° which means it is perpendicular to the base and hence it can be used as the height of the triangle.
=1/2 x18 x24 =216 square metres
