Question

A rectangle has an area of 25.2m2. One of the sides is 0.7m in length. Work out the perimeter of the rectangle.

Answer 1

Answer:

73.4m

Step-by-step explanation:

Area of rectangle=25.2m2

or, length x breadth = 25.2 m2

or, length x 0.7 = 25.2 m2 (one of the sides=0.7m)

or, length = 25.2/0.7

length = 36m

perimeter = 2 x (length+breadth)

perimeter = 2 x 36.7

perimeter = 73.4m

Answer 2

Answer:

The Perimeter of the Rectangle is 73.4 meter.

Step-by-step explanation:

Area of the rectangle formula:

$\huge{\boxed{\boxed{\red{\sf{Area of Rectangle=Length*Breadth}}}}}$

Now equating:

Let us take the Breadth as x.

Length * Breadth = Area of the Rectangle

Solving:

=> 0.7 * Breadth = 25.2

=> Breadth = 25.2 / 0.7

=> 36 meter

Formula for finding the perimeter of the rectangle:

$\huge{\boxed{\boxed{\red{\sf{Perimeter of Rectangle=2(l+b)}}}}}$

Now finding the Perimeter of the given rectangle as we know the measurements needed to find the perimeter:

Perimeter = 2 (l + b)

=> 2 (0.7 + 36)

=> (2) (36.7)

=> 73.4 meter

Therefore the Perimeter of the Rectangle is 73.4 meter.
