The area of a rectangle is 45 cm2. Two squares are constructed such that two adjacent sides of the rectangle are each also the s

Zielflug [23.3K]

Answer:

The lengths of sides of squares are 5 cm and 9 cm.

Step-by-step explanation:

Let the sides of rectangle be x and y .

Area of rectangle = Length × Breadth

Given : Area of rectangle = 45 cm².

⇒ x × y = 45

⇒ $x=\frac{45}{y}$ ........(1)

Two squares are constructed such that two adjacent sides of the rectangle

so squares have side x and y .

Area of square = side × side

Area of square with side x = x²

Area of square with side y = y²

Also, The combined area of the two squares is 106 cm².

⇒ x² + y² = 106

From (1) put value of x , we get,

$(\frac{45}{y})^2+y^2=106$

Solving for y ,

$(\frac{45}{y})^2+y^2=106$

$2025+y^4=106y^2$

$y^4-106y^2+2025=0$

$y^4-81y^2-25y^2+2025=0$

$y^2(y^2-81)-25(y^2-81)=0$

$(y^2-25)(y^2-81)=0$

$y^2-81=0$ or $y^2-25=0$

on solving we get y = 5 and y = 9

Also, x can be find by putting in (1),

⇒ $x=\frac{45}{5}=9$ and ⇒ $x=\frac{45}{9}=5$

⇒ x = 9 and x = 5

Thus, lengths of sides of squares are 5 cm and 9 cm.
