Question

The area of a square is three times the area of a rectangle. The length of the rectangle is 5 cms more than (5)^2 which is three times its breadth What is the perimeter of the square ?​

Answer 1

Answer:

Step-by-step explanation:

Breadth = x

Then Length = 3 times of breadth.

lenght = 3x

Given that

The perimeter of the rectangle =area of square = 625

perimeter of rectangle =2 (l+b)

625=2 (3x+x)

625/2=4x

625/2×4 = x

78.125 = x

Hence,

Area of rectangle = length × breadth

Area of rectangle = 3X × x

Area of rectangle = 3×78.125 × 78.625

Area of rectangle =18427.7 cm^2

Answer 2

Answer:

Step-by-step explanation:

Length of rectangle is 5cm more than 5²

Length = 30 cm (25+5)

Breadth = 10 cm ( as L is 3 times to b)

Area of Rectangle =300 cm²

Area of Square = 900 cm². ( as 3 times to area of rectangle )

Side of Square = 30cm

Perimeter = 30×4

= 120 cm
