Question

2. The length and breadth of a rectangle are in the ratio 3 : 2 and its perimeter is 20 cm. The area of the rectangle
(in cm) is
(a 24
(b) 48
(c) 72
(d) 96​

Answer 1

Answer:

24

Step-by-step explanation:

let length = 3x

Breadth = 2x

As we know tha perimeter of rectangle is

P = 2(l+b)

20 = 2(l + b)

20= 2(3x+2x)

5x = 10

X = 2

length = 3*2 = 6

Breadth = 2*2 = 4

Area of rectangle is

A = l*b

6*4

24 cm^ 2
