Sure, you have to ask the question first though
CDEF is a trapezium
ABCF is a rectangle and perimeter is20cm
BD=9cm
AB=6cm
EF=3cm
What is the area of CDEF
ABCF is a rectangle and perimeter is20cm
BD=9cm

What is the area of CDEF
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
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
nope
tell us da answer
