Answer 1

Area of the square $=(side{)}^2$
Perimeter of square $=4\ast \left(side\right)$

Perimeter of the rectangle $=2\ast (length+breadth)$
Area of the rectangle $=\left(length\right)\ast \left(breadth\right)$

Perimeter of triangle = (sum of three sides)
Area of triangle $=\frac{1}{2}\ast \left(base\right)\ast \left(height\right)$
