You posted the question twice ... I have repeated the answer here .. .
Find the area of all the sides:
10 x 9 = 90
9 x 8 = 72
1/2 x 6 x 8 = 24
1/2 x 6 x 8 = 24
6 x 9 = 54
Add them up:
90 + 72 + 24 + 24 + 54 = 264 square metres

Area of left over paper=area of rectangle - area of triangle
=132-24
=108inches^2
Okay so let’s start with number one you have 2 out of the 3 sides and you have to solve for the third
Let’s call the side you are looking for side A than the side with 13 side B and the side with 29 side C
So
B=13
C=29
A= ?
You would use the equation
A^2 + B^2 = C^2
So
A^2 + (13)^2 = (29)^2
13^2 = 169
29^2 = 841
So
A^2 + 169 = 841
A^2 = 672
A= 4 times the square root of 42
Or if yu need a estimated answer
A= 25.9
