What exactly are we solving?? the rest of the angles or the perimeter?
1^81, 9^2, 3^4. the others are rather to high or to low
The answer is actually 164.1 because I learned how to multiply this. :)
Answer:
W ≈ 5.2 cm
Step-by-step explanation:
Represent the length and width by L and W respectively.
Then L * W = 81 cm^2, and L = 3W.
Substituting 3W for L in the first equation, we get:
3W * W - 81 = 0, or 3W^2 - 81 = 0.
To make it easier to find the final answer, rewrite 3W^2 - 81 = 0 as
81
W^2 = ------- = 27
3
Then W (the width) is the positive square root of 27, or W ≈ 5.2 cm
18 is 6+n. The other one is 60 because n=60 and 60+6=66. 66 represents Chang's height.
