Answer:
Explanation:The length of a rectangle is 5 feet longer than it is wide. If each side is increased 5 feet, then the area is multiplied by 3. What was the size of the original rectangle? The width or short side is feet The length or long side is feet online
The Answer is
The original width=20/3
The length=(10+20/3)=50/3 ft
Given:
width=x ft
length=(x+10) ft
Area:
x(x+10) ft²
Step 1
Given that the sides are increased by 10, then the new dimensions will be:
width=(x+10) ft
length=(x+20) ft
Step 2
Therfore, the area will be:
(x+10)(x+20)=4×(x^2+10x)
solving for x we get:
x=-10 or x=20/3
Hence: the original width=20/3 and length=(10+20/3)=50/3 ft
