Question

the breadth of a rectangular park is 2/3 of its length. if the perimeter of rectangular park is 40m. find its length and breadth.​

Answer 1

Answer:

40 cm

Step-by-step explanation:

Let length be 'a' cm

Breadth = (2/3)*a

Perimeter of a rectangle = 2( length + breadth)

2(a+ 2a/3) = 40

2[(3a+2a)÷3]= 40

2(5a/3) = 40

2*5a = 40*3

10a = 40*3

a = 12

Length = 12 cm

Breadth = (2/3)*12 = 8 cm

Note:

• Where * is multiplication (x)

Verification:

Perimeter = 2(12+8) = 40 cm
