Answer 2

Given :-

• Length of the rectangle = 7.5 cm

• Breadth of the rectangle = 5.3 cm

To Find :-

• The area of the rectangle.

Formula used :-

• Area of rectangle.

Solution :-

Here, we have to find the area of the rectangle, and the length and breadth of the rectangle are given, so we will use the formula of area of the rectangle.

$\sf \underline{area \: of \: rectangle} \: = l \: \times \: b$

Where,

A = Area

L = Length

B = Breadth

On substituting the values -

A = L × B

A = 7.5 × 5.3

A = 39.75 cm²

$\therefore$ the area of the rectangle is 39.75 cm².

More formulae -

1. Perimeter of rectangle = 2(l + b)

2. Diagonal of rectangle = $\sf \: \sqrt{h} + \sqrt{b}$
