CDEF is a trapezium
ABCF is a rectangle and perimeter is20cm
BD=9cm
AB=6cm
EF=3cm
What is the area of CDEF



Answered by Senthu S
Okay so we know the perimeter is 20cm, that means using the rectangle formula for perimeter

Perimeter =2(Length +Width)

Substitute the numbers we have

20cm=2(6cm+Width)
20cm=12cm+2Width
4=Width (after rearranging it)

So we have found the answer for BC which is 4cm which makes CD 5 cm

At this point you use the Trapezium area formula
