What is it telling us to do- and what do we know?
To find the perimeter of the problem, add all side lengths together.
To find the area, add all the areas of the piece together.
Imagine your taking the piece apart.
Find the area of each separate piece.
to find the width of c and d, divide 70 by 14. That = 5
There are five separate widths-b- c- d and all in between, so we can safely assume each width is 14.
To find the area of b, multiply 50-12 by 14. 38*14=542
To find the area of c, multiply 25 by 14=350
To find the area of d, multiply 50 by 14, because at the top we can see its equal to 50. That =700
Then finally, to find the area of a, multiply 70 by 12 to get 840. Added all together, the total area is 2432.
To find the perimeter, we take all the data we've gathered about the side lengths and add it together. The total perimeter is 414.
Hope this helps!
