A rectangle has an area of 159.1m2 one of the sides is 3.7 in length work out the perimeter of the rectangle/
uysha [10]

Answer:

<h2>93.4 m</h2>

Solution,

Area of rectangle = 159.1 m^2

Length of rectangle = 3.7 m

Breadth of rectangle = ?

perimeter of rectangle = ?

Now,

Area of rectangle = 159.1 m^2

or, length * breadth = 159.1

or, 3.7 * breadth = 159.1

or, 3.7 breadth = 159.1

or, breadth = 159.1 / 3.7

breadth = 43 m

Again,

Finding the perimeter of rectangle:

perimeter of rectangle:

= 2 ( length + breadth)

= 2 ( 3.7 + 43 )

= 2 * 46.7

= 93.4 m

Hope this helps...

Good luck on your assignment...
