Question

Arun’s rectangular garden has a length of 40 m and a perimeter of 96 m. What is the breadth of his garden?

• A. 8 m
• B. 16 m
• C. 32 m
• D. 56 m

Answer 1

The correct option is A 8 m

Given,
Perimeter of the garden = 96 m
Length of the garden = 40 m

The perimeter of a rectangle is $2(l+b)$.

$\Rightarrow 2(40+b)=96$
$\Rightarrow 40+b=\frac{96}{2}$
$\Rightarrow 40+b=48$
$\Rightarrow b=48-40=8$ m

Therefore,
the breadth of the garden = $8$ m
