Remember: Perimeter of a rectangle = 2 x (length + breadth) Perimeter of a triangle - side + side + side 2. Use these formulae to calculate the perimeter of each of the following. Mento\\ moths 2,5cm 12 , S 125 5,1cm A C 7,5cm B 2,4cm 25 4,5cm 12,5cm a. Perimeter of square A = P= 25 cm+ 215 cm+ 2,som125m = 10cm b. Perimeter of rectangle B = P- 2( 12, 5) + 2( 75)= 25+15= 405 C. Perimeter of triangle C = P - 5, 1 + 4 5+ 24 /m.= 12 cm: W A farmer needs to fence his paddocks, so he divides his farm into regular polygons and applies his formulae for perimeter. Calculate the perimeter of each paddock and find the total cost if the fencing costs R75 a metre. 45m 80m A B 50m 65m 75m 4. A gardener wants to make a bed that has a perimeter of 24m. Which different options could he consider if he made a rectangular bed
