45 degreesAnswer:
Step-by-step explanation:
We need to identify the given data.
Given:
Width is unknown but it is the basis of the measurement of length.
Width = x
Length = 3x
Perimeter = 44cm
Perimeter is solved by adding all the sides of the rectangle. In rectangles, opposite sides are equal.
Perimeter = Length + Length + Width + Width
or simply: Perimeter = 2(Length+Width)
44cm = 2(3x + x)
44cm = 2(4x)
44cm = 8x
44cm/8 = 8x/8
5.5cm = x ⇒ width of the rectangle.
Since length is said to be three times the width, so ⇒ 3*5.5 = 16.5cm
Length = 16.5 cm
Width = 5.5 cm
To check: We use the Perimeter formula
P = 2(l+w)
44cm = 2(16.5cm + 5.5cm)
44cm = 2(22cm)
44cm = 44cm
