Find the perimeter and the area of a rectangle with the sides 4 7/20 m and 6 2/3 m.

Step-by-step explanation:

hello :

the area is 4 7/20m × 6 2/3 m =   continu

the perimeter is : (4 7/20m + 6 2/3 m)×2

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
