Measurement: Area & Perimeter of Composite Shapes
Find the area or perimeter of each composite (L-shaped or joined) figure.
- 1.An L-shaped room is formed by a 11 by 25 rectangle with a 7 by 12 rectangle cut from one corner. Find its area.
- 2.An L-shaped room is formed by a 14 by 17 rectangle with a 8 by 5 rectangle cut from one corner. Find its area.
- 3.An L-shaped room is formed by a 23 by 20 rectangle with a 5 by 10 rectangle cut from one corner. Find its area.
- 4.An L-shaped room is formed by a 11 by 17 rectangle with a 2 by 6 rectangle cut from one corner. Find its area.
- 5.An L-shaped room is formed by a 12 by 15 rectangle with a 4 by 2 rectangle cut from one corner. Find its area.
- 6.A composite shape is made of a 7 by 9 rectangle and a 12 by 10 rectangle joined together. Find its total area.
- 7.A composite shape is made of a 4 by 3 rectangle and a 9 by 15 rectangle joined together. Find its total area.
- 8.A composite shape is made of a 4 by 5 rectangle and a 13 by 14 rectangle joined together. Find its total area.
- 9.A composite shape is made of a 14 by 10 rectangle and a 15 by 3 rectangle joined together. Find its total area.
- 10.A composite shape is made of a 4 by 6 rectangle and a 9 by 9 rectangle joined together. Find its total area.
- 11.An L-shaped room is formed by cutting a rectangular notch from one corner of a 14 by 20 rectangle. Find the perimeter of the L-shape (cutting a right-angled notch from a corner does not change the total perimeter).
- 12.An L-shaped room is formed by cutting a rectangular notch from one corner of a 21 by 18 rectangle. Find the perimeter of the L-shape (cutting a right-angled notch from a corner does not change the total perimeter).
- 13.An L-shaped room is formed by cutting a rectangular notch from one corner of a 13 by 22 rectangle. Find the perimeter of the L-shape (cutting a right-angled notch from a corner does not change the total perimeter).
- 14.An L-shaped room is formed by cutting a rectangular notch from one corner of a 16 by 14 rectangle. Find the perimeter of the L-shape (cutting a right-angled notch from a corner does not change the total perimeter).
