This Grade 5 sheet pushes into composite shapes and triangle area. Students decompose L-shapes and T-shapes into rectangles, sum the parts, and apply A = 1/2 x base x height to triangles. Fill-in items mix decomposition and triangle problems, while a matching activity pairs each shape type with the correct formula or method. Whole-number side lengths and clear units keep the focus on strategy and correct labels.
Style:
Perimeter, Area, and Surface Area
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A triangle with base 8 cm and height 5 cm has area 20 sq cm.
2. An L-shape made of a 6x4 and a 3x2 rectangle has area 30 sq ft.
3. A triangle with base 10 m and height 7 m has area 35 sq m.
4. A T-shape with a 8x3 top and 4x5 stem has total area 44 sq in.
5. Half of base 12 ft times height 6 ft for a triangle gives 36 sq ft.
6. Two rectangles, 5x4 and 5x3, joined as an L have area 35 sq cm.
7. Triangle with base 9 in and height 4 in has area 18 sq in.
8. An L-shape decomposes into a 7x6 and a 2x3 rectangle; total area is 48 sq m.
9. A right triangle has legs 6 cm and 8 cm; its area is 24 sq cm.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Rectangle area
→ Decompose into rectangles, then add
Decompose into rectangles, then add
Triangle area
→ A = 1/2 x base x height
A = 1/2 x base x height
Square perimeter
→ A = length x width
A = length x width
L-shape area
→ P = 4 x side
P = 4 x side
