Question

if the length of a rectangle is 7 more than its breadth and its perimeter is 134 cm find the dimension of the rectangle

Answer 1

Step-by-step explanation:

Let the breadth of rectangle be x.

So, length of rectangle = x + 7

Now,

Perimeter = 2 ( l + b)

=> 134 = 2 ( x + x + 7)

=> 134 = 2 ( 2x + 7)

=> 2x + 7 = 67

=> 2x = 67-7

=> 2x = 60

=> x = 30

So, length of rectangle = 30 cm

Breadth of rectangle = 30 + 7 cm = 37 cm
