5th Grade Geometric Measurement Worksheets with Answers

I can see several 5th grade geometric measurement worksheets in the image. Let me identify what problems are visible and solve them:

Looking at the worksheets, I can see:
1. A perimeter worksheet with shapes to calculate perimeter
2. Surface area of cubes/rectangular prisms
3. Area of figures on grids (shaded shapes)
4. Area of triangles

Let me work through the visible problems:

Perimeter Worksheet:
- Shape A: Square with sides 6cm each
- Shape B: Pentagon with sides 2.5m, 2.5m, 2.5m, 2.5m, 3m
- Shape C: Rectangle with dimensions 5½ by 3¼

Area of Figures on Grids:
1. Pink T-shaped figure on grid
2. Blue arrow-like shape on grid

Area of Triangles:
- Triangle 1: Base = 8 miles, Height = 4.5 miles
- Triangle 2: Area = 20 square yards, Height = 8 yards, find base

Let me solve these systematically:

PERIMETER PROBLEMS:

A. Square: All sides = 6cm
Perimeter = 6 + 6 + 6 + 6 = 24 cm

B. Pentagon: Sides = 2.5m, 2.5m, 2.5m, 2.5m, 3m
Perimeter = 2.5 + 2.5 + 2.5 + 2.5 + 3 = 13 m

C. Rectangle: Length = 5½ = 5.5, Width = 3¼ = 3.25
Perimeter = 2(length + width) = 2(5.5 + 3.25) = 2(8.75) = 17.5 or 17½

AREA OF TRIANGLES:

Triangle 1: Base = 8 miles, Height = 4.5 miles
Area = ½ × base × height = ½ × 8 × 4.5 = 4 × 4.5 = 18 square miles ✓

Triangle 2: Area = 20 square yards, Height = 8 yards
20 = ½ × base × 8
20 = 4 × base
base = 20 ÷ 4 = 5 yards ✓

AREA ON GRIDS:

For the pink T-shape: I need to count squares or break it into rectangles
- Top rectangle: appears to be about 6 units wide × 2 units high = 12 sq units
- Bottom rectangle: appears to be about 2 units wide × 4 units high = 8 sq units
Total ≈ 20 square units

For the blue arrow shape:
This looks like a combination of shapes - would need to count carefully

SURFACE AREA:
Cube with side 6 feet: Surface area = 6 × (side²) = 6 × 36 = 216 square feet

Since the user didn't specify which problem to solve, I'll provide answers for all the clearly visible problems.

Final Answer:

PERIMETER:
A. 24 cm
B. 13 m
C. 17½ (or 17.5)

AREA OF TRIANGLES:
1. 18 square miles
2. Base = 5 yards

SURFACE AREA:
Cube (6 ft sides): 216 square feet
