Answer:
42cm²
Step-by-step explanation:
because if the perimeter of the rectangle is 28 then the length is 5, 5 - 11 = 6, the formula for finding the trapezium is to add the 2 parallel sides, half them, then times them with the length so your sum will look like this, 5+9=14, (i knew the other side was 9 as the length of AB is the same as the length of FC, which is the one of the parallel sides of the trapezium) then we do 14÷2=7, finally we times 7 by 6 which is 42cm²
Answer:
Step-by-step explanation:
area of rectangle=11×5=55 cm²
area of triangle=1/2×5×3=15/2=7.5 cm²
area of shaded region=55-7.5=47.5 cm²
