Answer:
130'²
Step-by-step explanation:
step 1) work out area of whole trapezium:
((a+b) x h) / 2
a and b are the two parallel sides
h is the perpendicular height (8)
a = 4+4+3 = 11
b = 23
a + b = 11 + 23 = 34
(a + b) x h = 34 x 8 = 272
272 / 2 = 136²
step 2) work out the area of rectangle
2 x 3 = 6²
step 3) take area of rectangle away from area of whole trapezium
136 - 6 = 130
130' ²
