Question

whitch is bigger in area: a rectangle whole length and breath are 15cm and 8cm respectively or a square of side 11cm?​

Answer 1

Answer:

a square

Step-by-step explanation:

area of rectangle= 15×8=120

whereas,

area of square= 11 × 11= 121

: hence, the square's area is bigger

Answer 2

$\LARGE\sf{\texttt{{{Required Answer:}}}}$

Given ☆

• A Rectangle with Length and Breadth 15 cm and 8 cm respectively

• A Square of side 11 cm

To Find ☆

• Shape bigger in area ( Square or Rectangle )

Formula Used ☆

• Area of Rectangle = Length × Breadth

• Area of Square = side × side

Solution ☆

To find which shape is bigger, first of all we need to find out the area of both the given shapes, and then compare which shape is bigger in area, so let's do it!

Area of Rectangle = Length × Breadth

Area of Rectangle = 15 × 8

Area of Rectangle = 120 cm²

Now, let's find out the Area of the Square!

Area of Square = side × side

Area of Square = 11 × 11

Area of Square = 121 cm²

On comparing both the areas, 121 cm² > 120 cm²

∴ Square with side 11 cm is greater than that of a Rectangle with Length 15 cm and Breadth 8 cm

$\LARGE\sf{\texttt{{{Important Formulas:}}}}$

Perimeter of Square = 4 × side

Perimeter of Rectangle = 2 × ( Length + Breadth )

Perimeter of Triangle = Sum of all sides

Area of Square = side × side

Area of Rectangle = Length × Breadth

Volume of Cube = side × side × side

Volume of Cuboid = Length × Breadth × Height

Note : We can also write the formula Area of Square = side × side as Area of Square = ( side )² and Volume of Cube = side × side × side as Volume of Cube = ( side )³
