The perimeter of a rectangle is 130 if one of its side is longer than the other side by 15m Find the length of each of side
Answers
Answer:
Let one side be x, then the other side is x+15
l = x
b = x+15
Perimeter = 2(l+b)
130 = 2(x + x + 15)
130/2 = 2x + 15
65 = 2x + 15
2x = 65 - 15
2x = 50
x = 50/2
x = 25 cm
Length = x = 25 cm
Breadth = x+15 = 25+15 = 40 cm

Answer:
- The length and breadth measure 40cm and 25 cm respectively
Step-by-step explanation:
Given:
- The perimeter of a rectangle is 130
- one of its side is longer than the other side by 15m
To Find:
- The length of each of side
Assumptions:
- let the breadth of the rectangle be x
- let the length of the rectangle be x + 15m
Full Solution:
→ Perimeter = 2 ( L + B )
→ 130m = 2 ( x + x + 15m )
→ 130m = 2( 2x + 15m)
→ 130m = 4x + 30m
→ 4x = 100m
→ x = 100m/4
→ x = 25cm
The length of the rectangle will be :
→The length of the rectangle will be = x = 15m
→The length of the rectangle will be = 25m + 15m
→ The length of the rectangle will be = 40m
The breadth of the rectangle will be :
→ The breadth of the rectangle will be = 1x
→ The breadth of the rectangle will be = 1(25m)
→ The breadth of the rectangle will be = 25m
Therefore:
- The length and breadth measure 40cm and 25 cm respectively
