Answer:
0.89 hours
Step-by-step explanation:
Micheal and his sister Mel share the task of mowing the grass in their yard.
Micheal mows 1/3 of the yard
= 1-1/3
= 2/3
Mel mows the rest portion
Mel can now mow 1/3 of the yard in one hour
Therefore the time taken by Mel to finish mowing the yard can be calculated as follows
= 2/3 ÷ 3/4
= 2/3 × 4/3
= 8/9
= 0.89 hours
Hence it will take Mel 0.89 hours to finish mowing the yard

Determine the area of K
First, we need to calculate the length of the rectangle J
This gives:
Divide both sides by 22
So, the length of the rectangle J is 20.
Since both shapes are similar, then:
Substitute the known values:
Express as fraction:
Make Length, the subject of formula
