Answer:
Step-by-step explanation:
Quadrilateral is divided into two triangles
Triangle 1:
Diagonal = 16m , h = 12m
Area1 = [tex]\frac{1}{2}base *height[/tex]
[tex]=\frac{1}{2}*16*12\\\\=8*12\\\\= 96 m^{2}[/tex]
Triangle 2:
Area2 = [tex]\frac{1}{2}*16*4[/tex]
= 8 * 4
= 32 square meter
Area of quadrilateral = 96 + 32 = 128 sq.m
