Question

The area of a rectangle with base, b = 16mm and perimeter, p = 50mm

Answer 1

Answer:

Given,

Base = 16mm

Perimeter = 50 mm

Let ,Length be x

Perimeter of Rectangle = 2(l+b)

2(l+b) = 50 mm

Putting value of b as 16 and l as x

$2(x + 16) = 50 \\ 2x + 32 = 50 \\ 2x = 18 \\ x = 9$

Therefore Length is 9 mm

Area of rectangle = Length × Breadth

Area

$= {(9 \times16) } {mm}^{2} = 144 {mm}^{2}$
