Answer:
first you have to find the values of the two sides of the rectangle. BC=5 cm
Area of a trapezium
= 1/2 x (5+9) x (11-5)
= 42 cm^2
Answer:
The answer is : 23.25 in ²
Step-by-step explanation:
There are 3 triangles with the same lengths: height = 5in and base = 5 in
There is one triangle: height = 4.3 in base = 5 in
Formula
Area = height x base / 2
For the triangles
Area = 5 in x 5 in /2 = 25 /2 = 12.5 in²
For the triangle
Area = 4.3 x 5 /2 = 21.5 /2 = 10.75 in²
Total surface area = 12.5 + 10.75 = 23.25 in²
