Question

a rectangle a with lenght 10cm and 5 cm similar to another rectangle b whose lenght is 30cm find the area of rectangle b​

Answer 1

Answer:

450 cm^2

Step-by-step explanation:

Let the breadth of rectangle b be x.

10:5 :: 30:x   (Given in question)

10x = 30 x 5   (Product of extremes = product of means)

x = 150/10

x = 15 cm

Area = 30 x 15 = 450 cm^2

Answer 2

Answer:

Area of 1 rectangle =length x breadth

10x5 =50

Area of 2 rectangle

30xb = 50

B = 50divided by 30

= 1.6 cm
