If we want to know the total distance when walking around this field, what do we use?

Perimeter

Convert this area measurement: 8,000,000 m2 (km 2)

8,000,000/1,000,000 = 8 km2

Convert this area measurement: 0.0051 m2 (cm2)

0.0051 x 10,000 = 51 cm2

What is the perimeter?

4.3 x 8 = 34.4 cm

What is the perimeter?

10 + 10 + 3 + 3 + 6 = 32 cm

The perimeter of a square box is 24 cm. What is the area of the box?

6 x 6 = 36cm2

Convert this area measurement: 700 cm2 (m2)

700/10,000 = 0.07 m2

A landscape gardener charges $20 per square metre of lawn. A lawn area is in the shape of a rhombus and its diagonals are 8 m and 14.5 m. What would be the cost of laying this lawn?

[Area = 58m2] [Cost of landscaping = $20m2] therefore, 20 x 58 = $1160.

What shape is this and what is the area

Rhombus, 9.61m2

Calculate the area of this composite shape

(10+16) x 7 /2 = 91 cm2

To decide the number of carpet tiles to cover the classroom floor, what will we use to measure?

Area

What is the perimeter?
