Answer:
13
Step-by-step explanation:
1) pythag formula(hint: memorize it now lol you'll have to SURVIVE off of this in higher studies ahaha)
a^2+b^2=c^2
where a=7
b=11
and
c=c
so substituting these values into our expression allows us to get:
7^2+11^2=c^2
49+121=c^2
170=c^2
we need to get the square root of 170 as we are finding c, not c^2
c=13.03

Answer:
26.4ft²
Step-by-step explanation:
I first converted the centimeter values to feet
140Cm x 30.48 = 4.59
70cm x 30.48 = 2.3
the paper required is approximately equal to the area of the pyramid.
area of pyramid is equal to area of triangle + base²
Are of triangle = 1/2 x b xh
= 4 x 1/2 x4.59x2.3 + (2.3)²
= 2 x 4.59 x 2.3 + 5.29
= 26.4 feet²
therefore it will take 26.4 feet² paper to make each tree, including the bottom.
