A square and rectangle have equal perimeter. Each side of the square measures 45 cm, while the lenght of the rectangle is 10 cm more than its breadth. If the lenght of the rectangle is assumed as x, then which equation correctly represents the given situation ?
Answers
Answer:
2*(x-10+x)=4x
Step-by-step explanation:
Perimeter of square= Perimeter of rectangle
Formula for square:4*side or 4s
Formula for rectangle:2*(length+breadth) or 2*(l+b)
Given, l=b+10
=>b=l-10
if L is x, then equation is
2*(x-10+x)=4x

Answer:
Hello There,
This is your answer.
Step-by-step explanation:
Side of the square = 45 cm
Length of the rectangle = x.
Breadth of the rectangle = x - 10
Perimeter of the square = Perimeter of the rectangle
Perimeter of the square = 4 × 45 = 180 cm
= Perimeter of the rectangle.
4s = 180 = 2 ( l + b )
2 ( l + b ) = 180
2 ( x + x - 10 ) = 180
x + x - 10 = 90
2x - 10 = 90
2x = 100
x = 100 / 2
x = 50
Length = 50 cm.
Breadth = 50 - 10 = 40 cm.
Formula = 4s = 2 ( x + x - 10 )
HOPE IT HELPS YOU!!!
