A <u>parallelogram</u> is a quadrilateral with parallel opposite sides. The main property of a parallelogram is that the opposite sides of the parallelogram are congruent.

1. Sides AB and CD are congruent, then

4x=18\\ \\x=\dfrac{18}{4}=4.5

2. Sides AD and BC are congruent, so

\dfrac{1}{3}x=7\\ \\x=7\cdot 3=21

3. Sides AD and BC are congruent, so

x+4=15\\ \\x+4-4=15-4\\ \\x=11

a sewing club is making a quilt consisting of 25 squares with each side measuring 30cm.if the quilt has 5 rows and 5 columns .de
LenKa [72]
To find the length of the sides of the quilt multiply the length of each square by how many squares make up that side
30 cm · 5 squares = 150 cm  (this is for both length and width because this quilt is a square)
For a square, perimeter=4·side, or all sides added together
p=4·150cm
p=600cm
Area of a square is length · width
A=150 cm·150 cm
A=22,500 cm²
