We know that an answer in square feet would require us to calculate the area. In order to calculate the area of a rectangle, we multiply the length times the width. So, we have 6 x 2 which is 12 Therefore, the area is 12 square feet.
For the area, it is length times width. 6X2=12, so that works out. For the perimeter, it is 2l+2w. 2(6)+2(2)=12+4=16, so that checks out as well.
It doesn’t matter which one is length and which one is width, unless you left out info. But u should be good putting them in any order. Hope that helps!
All you have to do is plug in the value of X in each expression for the sides of the triangle. Then after you figure out the values for the sides of the triangle in feet. Add the sides together to find the perimeter of the triangle.
