Answer:
In a rhombus, the diagonals bisect at right angles. That means half the diagonals form a right angle triangle then we can try the Pythagorean theorem. so -
one side of triangle = 6/2 =3 (half of the diagonal)
other side = 8/2 = 4
a^2 + b^2 = c2
3 ^2 + 4^2 = c^2
9+16 = c^2
c^2=25
c = = 5
the hypothenus forms one side of the rhombus and here the hypothenus is 5, so the lenght of a side is 5 !
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.
