Aleksandr-060686 [28]

Answer: d) 12 ft

Step-by-step explanation:

Let x be the width of the room , the the length of the room will be 2x.

We consider the shape of room is rectangle.

We know that the area of rectangle is given by :-

A=l\times w, where l is length and w is width.

Given : Area of the room is 288 square feet

\Rightarrow 288=2x\times x\\\\\Rightarrow\ 2x^2=288\\\\\Rightarrow\ x^2=144\\\\\Rightarrow\ x=-\sqrt{144}=\pm12

Since, width cannot be negative, so the width of the room = 12 feet.

Answer:

b = 30 yd is the answer.

Step-by-step explanation:

a = 40 yd

b = ?

c = 50 yd

According to the Pythagoras theorem,

a² + b² = c²

40² + b² = 50²

1600 + b² = 2500

b² = 2500 - 1600

b² = 900

b = 30 yd

∴ b = 30 yd is the length of the missing leg.
