Question

The length of the rectangle is 6m more than its breadth and perimeter of rectangle is 128m. Find the dimensions of the rectangle.

Answer 1

Explanation:

So, the breadth is x and the length is 6+x

so since there are four sides of a recatangle the equation will be:

6+x+6+x+x+x=128

12+4x=128

4x=128-12

4x=116

Divide both sides by 4

x= 29

The length will be= 29+6= 35m

so therefore

length= 35m

breadth=29m

Answer 2

Length = 35m

Breadth = 29m

Explanation:

So to find the answer you have to use algebra:

Let's say the breadth is x

And the length is (x+6)

128 = 2 (x + 6 + x)

128 = 2 (2x + 6)

128 = 4x + 12

4x + 12 = 128

4x = 128 - 12

4x = 116

x = 116/4

x = 29 m
