Answer 1

Answer:

Given

• Length of the rectangle ABCD = 5cm
• Breadth of the rectangle ABCD = 3cm

To find

• Area of rectangle ABCD = ?

Solution

• Area of rectangle = length X breadth

= 5 X 3

= 15cm sq.

Answer 2

REQUIRED ANSWER:

~Area of rectangle ABCD =15cm².

EXPLAINATION:

Here's the concept of area of rectangle is used. We have given length and breadth of rectangle and we have to find area of rectangle which we could easily find by applying formula of area of rectangle.

So let's start!

GIVEN:

• Length of rectangle=5cm
• Breadth of rectangle=3cm

TO FIND:

• Area of rectangle

SOLUTION:

★Area of rectangle=Length×breadth

Area of rectangle=5cm×3cm

Area of rectangle=15cm².

Hence the required area of rectangle is 15cm²

MORE FORMULAE TO KNOW:

=> Area of square=Side²

=> Area of circle=πr²

=> Area of triangle=½×base×height

=> Perimeter of square=4×Side

=> Perimeter of rectangle=2(L+B)
