Answer:
Let l be the length and w the width of the rectangle.
P as the perimeter and A as the area.
length of a rectangle is four times the width:
w = w
l = 4w
System of equation : 2l + 2w = P
Substitute:
2(4w) + 2w = 45
8w + 2w
10w = 45
w = 45 / 10
w = 4.5
Solve for l:
l = 4w
l = 4(4.5)
l = 18
Area:
A = lw
A = 18(4.5)
A = 81 in²
Answer: 1/12 yards
Step-by-step explanation:
The length of the pieces originally were 1/4 yards.
Jamie then cuts them into a 1/3 of their original length.
The new length is therefore:
= Original length * proportion of original length strips are cut into
= 1/4 * 1/3
= 1/12 yards
