Question

the breadth of a rectangular field is 150 metre its length is 2/ 1 by 3 times the breadth find the perimeter of the rectangle​

Answer 1

Answer:

Length of rectangle be L

Breadth of rectangle be B

Perimeter of rectangle be P

Area of rectangle be A

P = 150cm

L/B = 3/2

L = 3x

B = 2x

Where x is any constant to be multiplied to get the correct length and breadth of rectangle.

P = 2(L+B)

150 = 2(3x+2x)

75 = 5x

x = 15cm

Length(L) = 3*15 = 45cm

Breadth(B) = 2*15 = 30cm

A = L*B

A = 45*30

A = 1350 cm^2
