Question

In the inner part of a rectangle there are 9 square and legth of square a is 7 cm find the area of rectangle pqrs​

Answer 1

✬ Area = 441 cm² ✬

Step-by-step explanation:

Given:

• There are 9 squares inside the rectangle.
• Measure of each side of square is 7 cm.

To Find:

• What is the area of rectangle ?

Solution: Here if we add the area of all 9 squares together then we will get the area of rectangle.

As we know that

★ Area of Square = side² ★

• Each side is of 7 cm.

$\implies{\rm }$ Ar. of each square = (7²)cm²

$\implies{\rm }$ Area = (7 $\times$ 7)cm²

$\implies{\rm }$ Area = 49 cm²

Now, area of each square is 49 cm². Therefore,

➟ Area of 9 similar squares = 9(area of each square)

➟ Total area = 9(49) cm²

➟ Total area = 441 cm²

As it is mentioned earlier that area of all 9 squares together will form area of rectangle.

Hence, area of rectangle is of 441 cm².
