Question

The difference of sides of two squares is 12cm and the sum of the sides is 20cm What is the difference of the areas? find the length of sides of both squares?​

Answer 1

Answer:

Explanation:

Let the side of square 1 be x and side of square 2 be y

Area of square 1 =

Perimeter of square 1 =

Area of square 2 =

Perimeter of square 2 =

The difference of areas of two squares is 549 cm square.

--- 1

The difference of their perimeters is 12 cm

Substitute the value of x in 1

(y+18)(y-15)=0

y= -18,15

Since side cannot be negative

So, side = y = 15 cm

x=3+y=3+15=18 cm

Hence the sides are 15 cm and 18 cm
