Question

the length of a rectangle is twice of its breadth if its perimeter of its 108 cm find the dimensions of the rectangle and area of rectangle

Answer 1

Hii here is your answer
let breadth=x

perimeter of rectangle = 2 (l + b)
= 2 (2x + x)
108cm = 2 × 2x + 2 × x
= 4x + 2x
= 6x
6x = 108cm
x = 108/6
breadth = 18
length = 18 × 2
= 36

Area of rectangle = l × b
= 36 × 18
= 648 answer
