Question

*The side of a square is 5 cm and the area of ​​a rectangle is twice the area of ​​this square. So what is the area of ​​the rectangle?*​

Answer 1

Given

• Side of Square = 5cm
• Area of Rectangle =2 × Area of Square

To Find

• Area of Rectangle

We know that

$Area\ of\ Square= (Side)²$

$Area\ of\ Square= {5}^{2}$

$Area\ of\ Square= 25cm ^{2}$

• It is Given area of a rectangle is twice the area of this square

${Area \: of \: Rectangle= 2× Area \: of \: Square }$

${Area \: of \: Rectangle= 2× 25 }$

${Area \: of \: Rectangle= 50cm ^{2} }$

• Hance the area of Rectangle is 50cm²

Answer 2

Answer:

Area of a square =(side)²

Side = 5 cm

Area =( 5)² =25cm²

If side is doubled then ,

5*2= 10 cm

Area = (10)² = 100 cm²

100/25 = 4

So the area increases by 4 times when the side is doubled.
