(Sides meet at right angles.)
3 mm
3 mm
5 mm
1 mm
2 mm
4 mm

Answer 1

Divide into two rectangle

In the below one

• L=1+3=4mm
• B=2mm

Area=4(2)=8mm^2

In above one

• L=5-2=3mm
• B=3mm

Area=3(3)=9mm^2

Total area

• 9+8=17mm^2

Answer 2

• 17 mm²

Explanation:

An easy method is to subtract the areas of two rectangles, 5x4 and 3x1:

• 5*4 - 3*1 =
• 20 - 3 =
• 17 mm²
