Rectangle has four sides. The total weight of the circle is 20 grams.
A rectangle is a 2D shape that has four sides, and the pair of opposite sides are equal and parallel to each other.
As it is given that the weight of the rectangle is 80 grams, and a rectangle is made up of two triangles. Therefore, the weight of each triangle can be written as,
[tex]\text{Weight of the reactangle} = \dfrac{\text{Total weight of the reactangle}}{\text{Number of Triangles}}[/tex]
[tex]\text{Weight of the reactangle} = \dfrac{80}{2} = 40\rm\ grams[/tex]
It is given that the total weight of the triangle is double the weight of the circle. therefore, the relationship can be written as,
[tex]\text{Weight of the triangle} = 2 \times \text{Weight of the circle}[/tex]
[tex]40= 2 \times \text{Weight of the circle}\\\\\text{Weight of the circle} = 20\rm\ grams[/tex]
Hence, the total weight of the circle is 20 grams.
