to find the area of the rectangle, do A=lw which is 4x13=52. to find the area of the triangle, first find the height. this is 13-6=7. now do A=bh/2 which is (5x7)/2=17.5. 17.5+52=69.5 which is your answer. DONT OPEN ANY LINKS ON HERE, ITS A VIRUS
First you calculate the area of the rectangle.
It‘s simply one side times the other side.

In your task this would be:
4ft x 13ft = 52 square ft

Now you have to calculate the area of the triangle. The formula for this is: Height x Length of the base x 1/2

So in your task this would be:
7ft x 5ft x 1/2 = 17.5 square ft

(you get the 7ft by subtracting 6ft from 13ft, which results in the height of the triangle)

Now you just add those two surfaces areas together:
52 square ft + 17.5 square ft = 69.5 square ft
