How tall is a person that casts a 9 foot shadow?
Depends on the time of day (the angle of the sun). Think of the person as being at a right angle to the ground, and the shadow being the other side. The distance from the person's head to the end of the shadow is the hypotenuse. (a^2 + b^2= c^2) a= height of person, b= shadow. If you have the angle of the sun to the ground, you can use Sine/ Cosine to calculate the length.
What is 54 feet by 10 legs and 20 arms?
The answer depends on what you are actually asking. If you mean 54 ft x the length of 10 legs + the length of 20 arms, then you can express it as "54 ft x (the length of 10 legs + the length of 20 arms)". If you know the actual length of each leg & each arm, then you could add the lengths of each leg & the lengths of each arm & and you could maken an expression such as: "54 ft x (TL leg ft + TL arm ft) If you know the average leg length & average arm length, then you could maken an expression such as: "54 ft x (10 x aver leg len + 20 x aver arm len) Lastly, if you know such lengths, you could multiple 54 x TL length of the appendage to arrive at total square feet number.
