IGCSE Grade 5 Maths Use area and perimeter to determine cost
|
You need to find the area of square i.e \\((side)^2\\)
(Area of 4 rectangular walls x 3 pounds) + ( Area of 1 rectangular ceiling x 2 pounds )
21 times 5£
( Area + perimeter) x 3
Perimeter of square = 4 times the side
Perimeter of rectangle = 2 ( length + width )
Area of rectangle = length times width. Area of square = side times side
Find the perimeter first and then multiply the perimeter by $2.
Find perimeter by adding all the sides and then times by 6.
total cost = perimeter times per metre rate of fencing
