Answer:

420 unit^2.

Step-by-step explanation:

By Pythagoras theorem:

37^2 = 35^2 + w^2 where w = the width.

w^2 = 37^2 - 35^2

w^2 = (37 + 35) (37 - 35)

w^2= 72 * 2 = 144

w = 12 units.

So the area = 12 * 35

= 420 unit^2.

1)
The formula for the area of a rectangle is:

A=l*w

Since we know both the length, 15, and the area, 150, we can solve for the width.

150=15*w
Divide both sides by 15
10=w

The width is 10ft

Answer= The Dimensions of the rug are 10ft by 15ft

2)
The formula for the area of a rectangle is:
A=l*w

To solve for this problem, we need to subtract the area of the rug, from the area of the room.

A(room)-A(rug)=A(remaining)

We still don't know the area of the entire room, so lets solve for that

A(room)=l*w
A(room)=25*20
A(room)=500sq ft

Now we can search for the remaining area...

A(room)-A(rug)=A(remaining)
500-150=
350 sqft

Answer=350 sqft
