<h3>Question:</h3>
The length of a rectangle is 6 metres more than its breadth. the perimeter of the rectangle is 60 metres . find the length and breadth of the rectangle.
<h3>To find:</h3>
<h3>Given:</h3>
- length of a rectangle is 6 metres more than its breadth
- perimeter = 60 m
<h3>Let:</h3>
<h3>Answer:</h3>
We know:
<u>Perimeter = 2(L+B)</u>
by using this formula we can find value of x.
Let's Verify whether value of x is correct or not
insert Value of x
Hence verified
First let's find value of length :
- Length = 6+x
- Length =6+12
- <u>L</u><u>ength = </u><u>18</u><u> </u><u>cm</u>
Now Let's find value of breadth:
- Breadth = x
- <u>B</u><u>readth = 12</u><u> </u><u>cm</u>
Step-by-step explanation:
x= number of lawns Jonas needs to mow
40x+650=6750
Now Solve!!!
First subtract 650 from both sides
40x=6100
Now divide by 40
x=152.5 lawns
Jonas can't mow 1/2 a lawn, so he would have to mow 153.
