Question

A rectangle has an area of 159.1m2. One of the sides is 3.7m in length. Work out the perimeter of the rectangle.

Answer 1

93.4 m

Solution,

Area of rectangle=159.1 m^2

Length=3.7 m

Breadth=?

Now,

`area \: of \: rectangle = l * b \\ or \: 159.1 = 3.7 * b \\ or \: 159.1 = 3.7b \\ or \: b = (159.1)/(3.7) \\ b = 43 \: m`

Again,

Perimeter of rectangle:

`2(l + b) \\ = 2(3.7 + 43) \\ = 2 * 46.7 \\ = 93.4 \: m`

Hope this helps...

Good luck on your assignment..
