The area of rectangle is : 60.0
5 x 12 = 60 sq. cm
Four measurements
Area = 0.5*10*12 = 60 square cm
Area = 35 cm2 and one side = 5 cm => other side = 7 cm So perimeter = 2(5 + 7) = 2*12 = 24 cm
It is 12*5 = 60 square centimetres.
The area of rectangle is : 60.0
The height would be 4.8 cm.
60/12 = a height of 5 cm
5 x 12 = 60 sq. cm

A 5 cm x 5 cm square has an area of 25cm².
Area = 0.5*10*12 = 60 square cm
Area = 35 cm2 and one side = 5 cm => other side = 7 cm So perimeter = 2(5 + 7) = 2*12 = 24 cm
12 cm
Using Pythagoras: distance from (0, 0) to (12, 5) = 13 which is the radius Circumference: 2*pi*13 = 81.691 cm to three decimal places Area: pi*13^2 = 530.929 square cm to three decimal places
Each side = 20/4 = 5 cm Area = 5*5 = 25 square cm
