Answer:
2700
Step-by-step explanation:
Given,
Ratio of sides of rectangle=4:3
Perimeter of a rectangle=210
Let,
Length of the rectangle=4x
Breadth of the rectangle=3x
Perimeter of a rectangle=2(l+b)
210 =2(4x+3x)
210=2(7x)
210=14x
210/14=x
15=x
Length of the rectangle=4x
=4(15)
=60
Breadth of the rectangle=3x
=3(15)
=45
Area of the rectangle=lb
=(60)(45)
=2700
