Question

Length of a rectangle is 3 more than it's breadth, if perimeter of the rectangle is 38 cm.Find the area?

Answer 1

Answer:

67.6875

Step-by-step explanation:

Let the dimensions of the rectangle be x and 3x

2(x+3x)=38

2 X 4x = 38

x = 38/8 = 19/4

Area = 3x*x = 3x²

=3*$\frac{19}{4}$*$\frac{19}{4}$

= 1083/16

= 67.6875
