Area is a measure of the surface area of ​​a shape. To find the area of ​​a rectangle or square, you need to multiply the length and width of the rectangle or square.

Solution according to the given information in the question:

Area of rectangle R = 80

Ratio of rectangle R = 30

Ratio of rectangle S = 7

Area of rectangle S

= (7/30)×80

Multiply the fraction (7/30) by 80:

(7/30) × 80 = (7 × 80) / 30

Calculate the product:

7 × 80 = 560

Divide the product by 30:

560 / 30 = 18.66666666668
