Week 308 (4th August 2023)

Helena likes to get cosy under a blanket while watching TV.   

Helena has a rectangular blanket made from 100% wool.  

The wool in the blanket has a mass of 136g per m2.  

The mass of his blanket is 952g.  

The width of his blanket is 2.5m.  

Calculate the length of Helena’s blanket. 


952/136 = 7m2  

Area of rectangle = length x width        7 = 2.5 x length          

length = 7/2.5 = 2.8m
