Part B
Using squares 1, 2, and 3, and eight copies of the original triangle, you can create squares 4 and 5 €. Keep the square 4 and square 5
window open. You will need them to complete the rest of the tasks in this section.
What are the side lengths of square 4 and square 5 in terms of a and b? Do the two squares have the same area?

The areas of two similar triangles are 72dm2 and 50dm2. the sum of their perimeters is 226dm. what is the perimeter of each of these triangles?

The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. the function below shows the relationship between f(x) and x: f(x) = 10(1.3)xwhich of the following graphs best represents the function? graph of f of x equals 1.3 multiplied by 10 to the power of x graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity graph of f of x equals 10 multiplied by 1.3 to the power of x graph of f of x equals 1.3 to the power of x

What is the area of the shaded sector?
