1. ## area of shape

hi, i need to find the area of this shape:

im not really sure what to do for this but could i do, 7x11=77 77/6=12.8??

2. The area of a trapezium is given by $A = h \left(\dfrac{a+b}{2}\right)$ where

• a and b are the parallel sides
• h is the perpendicular height

In this question a = 11, b = 7 and h = 6

I get an area of 54

3. i don't understand! i understand 11+7=77/2=35.8 but how do i use the 6?

4. 11+7 = 18 not 77!

in the formula above h is the perpendicular height and in your diagram 6 is the perpendicular height

5. oh sorry, misread it, though it said 11 x7

thanks alot i understand now.
