Cherry Hill concrete driveway layout example.

20 × 32 ft rectangle plus triangle with 10 ft base and 12 ft perpendicular height

The entered footprint totals 700 ft². At an illustrative 5 in input, the calculated volume is 10.80 yd³ before any extra allowance.

These are geometry inputs, not a recommendation about construction thickness. Final measurements, design, quantities and supplier order increments require the actual project team.

The triangle contributes 60 ft²; the rectangle contributes 640 ft².

The example assumes the shapes do not overlap. Correct that assumption if using your own sketch.

The shape calculation says nothing about actual slope, access, base or drainage; those need a site assessment.

• Are the dimensions perpendicular where the formula requires it?
• Do any sections overlap?
• What actual levels and interfaces need professional measurement?

Does the sketch describe distinct, correctly measured shapes without double-counting?

Rectangle: 20 × 32 ft gives the example 640 ft² rectangular section.

Triangle: 10 × 12 ÷ 2 gives the example 60 ft² triangle; the height must be perpendicular to the base.

Whole project: Actual overlap, boundaries, levels, demolition, drainage and access before treating 700 ft² as final.

Geometry arithmetic does not identify the lot’s slope or establish a specified joint arrangement.

Before work: permissioned condition photographs, a measured sketch, agreed scope and the source of the actual design.

During work: true removal, base/preparation, placement, finish, joints and protection evidence, with facts distinguished from assumptions.

At completion: actual provider review, approved photographs, project-specific care instructions and a clear record of what was and was not verified.

Replace the example dimensions and conditions with your own observed information. Keep unknowns open and let a qualified assessor determine the appropriate solution.
