Question

The area of a rectangle is 256.5m2. if the length is 18m, what is the perimeter of the rectangle

Answer 1

256.5/18= 14.25

(14.25x2)+(18x2)= 64.5m

Answer 2

Perimeter of the rectangle is 64.5 m

Further explanation

To solve the above questions, we need to recall some of the formulas as follows:

Area of Rectangle = Length × Width

Perimeter of Rectangle = 2 × ( Length + Width )

Let us now tackle the problem !

Given:

Area of Rectangle = A = 256.5 m²

Length of Rectangle = L = 18 m

Unknown:

Perimeter of Rectangle = P = ?

Solution:

This problem is about Area and Perimeter of Rectangle.

Let's find the width of Rectangle.

$\texttt{Area of Rectangle} = \texttt{Length} \times \texttt{Width}$

$256.5 = 18 \times \texttt{Width}$

$\texttt{Width} = 256.5 \div 18$

$\texttt{Width} = \boxed {14.25 ~ \texttt{m}}$

Let's find the perimeter of Rectangle.

$\texttt{Perimeter of Rectangle} = 2 (\texttt{Length} + \texttt{Width})$

$P = 2 ( L + W )$

$P = 2 ( 18 + 14.25 )$

$P = 2 ( 32.25 )$

$P = \boxed {64.5 ~ \texttt{m}}$
