Question

The length of a rectangle is three times its
bredth. The Perimeter of the rectangle is
equal to that of a square whose area is a
625 cm². Find the area of the rectangle.​

Answer 1

Answer:

468.75

Step-by-step explanation:

Area of square = 625 cm square

side = √625

= 25 cm

perimeter = 25*4 = 100 cm

L = 3x  ,  B = x

100 = 2(3x+x)

100/8 = x

x = 12.5 cm then 3x = 37.5 cm

area = 12.5*37.5

        = 468.75 cm square
