composite areas in tiling

What is an area?

• The area is the total volume of a solid.
• The area is the distance around a shape.
• The area is the weight of an object.
• The area is the measure of a surface in square units.

What is the rule to calculate surface area?

• Surface area is calculated by summing the areas of all faces of the object.
• Surface area is calculated by multiplying the length by the width.
• Surface area is determined by the perimeter of the object.
• Surface area is the same as the volume of the object.

How can we break a compound area down to work out the area of it?

• Calculate the area of the largest shape only.
• Use a ruler to measure the perimeter.
• Divide the compound area into simpler shapes, calculate each area, and sum them.
• Estimate the area based on visual inspection.

What Formula do we use to work out the area of a rectangle?

• Area = length ÷ width
• Area = 2 × (length + width)
• Area = length + width
• Area = length × width
