Hope this helps let me know if it does :)
You do 9+3 which equals 12 then you multiply that by 4
Answer:
68cm^2
Step-by-step explanation:
<h2>A trapezium is a type of quadrilateral with the two opposite sides parallel.</h2>
Area of a trapezium= 1/2(sum of parallel sides)×height
Area of the trapezium= 1/2(5+3)×17
Area of the trapezium= 1/2(8)×17
Area of the trapezium=4×17= 68cm^2
Answer: 288cm²
Explanation:
In the given trapezoid, there are 2 right angled triangles and 1 rectangles.
So,
area of trapezoid
=area of 2 right angled triangles +1 rectangle
=2×[16×3]/2 + 15×16
=48+240
=288 cm²
Note:
Area of right angled triangle
=(base× height)/2
&,
Area of rectangle
= length ×breadth
