measures 20 cm as shown in the figures:
A
2x
B
P
Q
20 cm
3x
S
D
C
If the perimeters of both are equal, find the length and breadth of the rectangle.​

Answer 1

Step-by-step explanation:

Peri.meter of square = 20×4=80cm

ATQ

Perimeter of square is same to perimeter of rectangle

so let the length and breadth be 3x and 2x .

2×(3x+2x)= 80cm

5x=80/2=40

x=40/5=8

3x=8×3=24cm

5x=8×5=40cm
