Please help mE Please

Answer 1

It is simple you just have to find the area of every triangle ...and its clear that all of them are right angle triangle ..you can simply use this formula AREA OF TRIANGLE= 12 x base x height

And then that last quadrilateral DFHE in this you already have the measure of the length of DF =20,FH=70,EH=30 so to find the area you will have to draw a perpendicular from D on the segment EH and name it E' AND THIS WILL MAKE IT A RECTANGLE WITH LENGTH 70 and breadth 20 .Now u just have to subtract 30-20 which is equal to 10 and this is the base of your last triangle which will be DEE' now after you have found the area of every figure you just have to add them and this will give you the area of this figure ...

Area CGB =1750m

Area CGB =1750mArea AGB = 2000m

Area CGB =1750mArea AGB = 2000mArea EAH = 750m

Area CGB =1750mArea AGB = 2000mArea EAH = 750mArea DFC = 300m

Area CGB =1750mArea AGB = 2000mArea EAH = 750mArea DFC = 300mArea DFHE' = 1400m Area DEE' = 350m

Area CGB =1750mArea AGB = 2000mArea EAH = 750mArea DFC = 300mArea DFHE' = 1400m Area DEE' = 350mNow 1750+2000+750+300+1400+350=

6550m

So the total area will be 6550m
