Answer:
I think that the Linear system of equations can be used to find the cost.
Step-by-step explanation:
Step-by-step explanation:
The area of a rectangle is 171 m²
Let l is the length and b is the width of the rectangle
It width is 10 m less than the length. So,
b = l-10 ...(1)
Area of a rectangle is given by :
or
l = 9 m or l = 19 m
If l = 9 m,
b = 9-10 = -1 m (can't be possible)
If l = 19 m
b = 19-10 = 9 m
So, the length an the breadth of the rectangle is 19 m and 9 m respectively.
Answer:
Step-by-step explanation: I did a formula to get the answer
2x-10=5x-100
2x=5x-90
I subtracted 100-10 and then got 90
3x=90
3x/3x=90/3
x=30
