Question

The area of a rectangular sheet of paper is 20 cm². Its length is 5 cm. Find its width.
Also find the perimeter of that sheet

Answer 1

Area of rectangular sheet = 20 cm²
Length of rectangular sheet = 5 cm

We know that,
Area of rectangle = length $\times$ breadth
20 = 5 $\times$ breadth
Breadth = $\frac{20}{5}=4$ cm
$\therefore$ Breadth of rectangle is 4 cm
Perimeter = 2(length + breadth)
= 2(5+4)
= 18 cm
