Question

Sides of a rectangle are 3x and 4x and its area is 588 cm². Find the perimeter of the rectangle.​

Answer 1

Answer

Area of rectangle-588cm^2

Length=3x and Breadth =4x

Area=Length*Breadth

588=3x*4x

12x^2=588

x^2=49

x=7cm

Length=3*7=21 cm, Breadth=4*7=28cm

Now,

Perimeter of rectangle=2{length+breadth}      [Putting the values on the formula]

Perimeter=2[21+28]

Perimeter=2*49

Perimeter=98 cm. ANS
