Question

The length of a rectangle is 10 m more than its breadth. If the perimeter of rectangle is 80 m, find the dimensions of the rectangle.

Answer 1

Answer:25

Step-by-step explanation:

80m = side1 + side2 + side3 + side4. Now a rectangle has 2 sets of equal length sides. And we are told that the length is 10m more than it's breadth. So s1 = 15m, s2 = 15m, s3 = 25m, s4 = 25m.

Answer 2

Answer:  

The Correct Answer is 5 m and 10 m

Step-by-step explanation:

Let the breadth of the rectangle be: x  

Then the length of the rectangle is; x + 10  

Perimeter of rectangle: 2 ( L + B )  

ATQ,  

80 m = 2 ( x + x + 10 )  

40 = 4x + 20  

20 = 4x

x = 5  

The Breadth is 5 m and Length is 10 m
