Question

Work out the area of a rectangle with base, b = 14mm and perimeter, P = 52mm.​

Answer 1

Area of rectangle is 168$mm^2$

Step-by-step explanation:

Given,

Base = 14mm

Perimeter = 52mm

We will find length first to calculate area of rectangle.

Let l be the length of rectangle.

As we know,

Perimeter = 2(length + base)

52=2(l+14)

$Dividing\ both\ sides\ by\ 2\\\frac{52}{2}=\frac{2}{2}(l+14)\\26=l+14\\Subtracting\ 14\ from\ both\ sides\\l+14-14=26-14\\l=12mm$

Now,

Area of rectangle= Length * Base

$Area\ of\ rectangle = 14*12\\Area\ of\ rectangle= 168\ mm^{2}$

Area of rectangle is 168$mm^2$
