Perimeter: 28.5 inches
Area: 33.75 in^2
We are given that Marquez and Victoria are making pinwheels. Each of them is composed of 4 triangles with the dimensions as shown below.
Using the given dimensions, we will find the perimeter and the area of this triangle. Let's start with the perimeter.
Perimeter : 11+ 8.5+ 9=28.5 The perimeter of this triangle is 28.5 inches.
Now let's recall the formula for the area of a triangle. In this formula b is the base and h is the corresponding height. A = 1/2bh Let's look at the picture. We will label the height corresponding to the base that has a length of 9 inches as h.
Calculate power
LHS-16=RHS-16
sqrt(LHS)=sqrt(RHS)
sqrt(a^2)=a
