Answer:
First find the area of the biggest shape in the diagram which is the rectangle:
Area Rec = Length x Breath
= 80 x 15
= 1200 square units.
Find the area of the triangle:
Area Tri = (1/2) x base x height
= (1/2) x 10 x 15
= 75 square units
Find area of the small rectangle at the left hand side of the big rectangle:
Area Rec = Length x Breath
= 25 x 25
= 625 square units
Since we found all the areas of everything we can add and subtract some areas to find the area we really want:
so to get area of this shape we have to:
Area Big Rectangle - Area of Triangle - Area of Small Rectangle = Shape
1200 - 625 - 75 = 500
Area of shape = 500 square units.
I don't know if the length of the big rectangle is 60 or 80 but you should know how to do it.
Hope this helps. Good luck!
