Check the picture below.
since in a rhombus the diagonals bisect each other, thus EC = EA.
now, the rhombus is simply 4 congruent triangles, we know the base and height of one of them, thus

Answer:
839393
Step-by-step explanation:
8x10 = 80
4x4 = 16
2x4 divided 2 = 4
80+16+ 4 = 100
Answer:
Step-by-step explanation:
Remark
Interesting detail.
Origami Paper is square -- perfectly.
So the properties listed will be related to a square.
Givens
Area = 35 in^2
Formulas
Area = s^2 where s is the length of 1 side.
Perimeter = 4s
Solution
<u>Area = s^2 = 35</u>
s^2 = 35 Take the square root of both sides.
√s^2 = √35
s = 5.91
<u>Perimeter = 4s</u>
s = 5.91
Perimeter = 4*5.91
Perimeter = 23.66
The way the question is worded, the answer you should submit is
Perimeter = 4 * √35
Answer:
29.787%
Step-by-step explanation:
The computation of the percentage that spend on yellow pages is shown below:
= Yellow pages ÷ Total advertising cost
= $700 ÷ ($700 + $600 + $650 + $400)
= $700 ÷ $2,350
= 29.787%
