Perimeter is the sum of the lengths of a shape.

Based on the definition of perimeter, we simply add the lengths of the square.

Perimeter $=$ $=$ $L + L + L + L$ $L+L+L+L$

$=$ $=$ $4 \times L$ $4xxL$

$=$ $=$ $4 L$ $4L$ cm

$4 L$ $4L$ cm

Perimeter is the sum of the lengths of a shape.

Based on the definition of perimeter, we simply add the lengths of the triangle.

Perimeter $=$ $=$ $x + x + y$ $x+x+y$

$=$ $=$ $(2 \times x) + y$ $(2xxx)+y$

$=$ $=$ $2 x + y$ $2x+y$

$2 x + y$ $2x+y$

Perimeter is the sum of the lengths of a shape.

Based on the definition of perimeter, we simply add the lengths of the trapezoid.

Perimeter $=$ $=$ $x + y + z + z$ $x+y+z+z$

$=$ $=$ $x + y + (2 \times z)$ $x+y+(2xxz)$

$=$ $=$ $x + y + 2 z$ $x+y+2z$

$x + y + 2 z$ $x+y+2z$
