Work out the area of the trapezium ABDE.
5 months ago
Q:
Work out the area of the trapezium ABDE.
Accepted Solution
A:
the two triangles seen in the picture are simular (congruent) and one is enlarged.
scale factor= 9÷6 = 1.5
8×1.5 =12 (the side length of the triangle)
12-8=4 (bottom side length of trapezium)
area of trapezium= 1/2× ((a+b)×h)
1/2×((6+9)×4)=24cm^2
