A rectangle that is 2cm by 4cm has an area of 8cm. It also has a perimeter of 12cm.
26cm
perimeter = 8+8+5+5 = 26cm
Width of rectangle: 144/18 = 8cm Perimeter of rectangle: 2*(18+8) = 52cm
Perimeter = 20+8+20+8 = 56 cm.....
A rectangle that is 2cm by 4cm has an area of 8cm. It also has a perimeter of 12cm.
26cm
perimeter = 8+8+5+5 = 26cm
Width of rectangle: 144/18 = 8cm Perimeter of rectangle: 2*(18+8) = 52cm
34 cm (with the help of Pythagoras' theorem)
Perimeter = 20+8+20+8 = 56 cm.....
12+12=24 8+8= +16 The perimeter =40cm2
4cm by 13cm
2*(40 + 8) = 2*48 = 96 cm.
P = 46 cm A = 120 sq cm
Perimeter is the total of all the sides. Let's assume your part-question relates to a rectangle. Four sides: 2 x 8cm and 2 x 15cm. I'm sure you can work it out from there...
52 cm
