Question

The area of a rectangle is 424242 square millimeters. The length is 777 millimeters.
What is the perimeter of the rectangle?

Answer 1

Answer:

area=424242mm

length=777mm

so, breadth= 424242÷777=546mm.

perimeter=2646mm

Answer 2

Answer:

Perimeter = 2646 millimeter

Step-by-step explanation:

Given

Area of rectangle = 424242 sq mm

Length of rectangle = 777 mm

Let width of rectangle = W mm

Now

As we know that,

Area of rectangle = length × width

So

424242 = 777 × W

=> W = 424242 / 777

=> W = 546 mm

Now

Perimeter of rectangle = 2(length + width)

=> perimeter of the rectangle = 2(777 + 546)

=> perimeter of the rectangle = 2 × 1323

=> perimeter of the rectangle = 2646 mm
