Question

the length of a rectangle is twice its breadth if the perimeter of the rectangle is 36 cm find the sides of rectangle​

Answer 1

hey the answer is ....


length be 2x

perimeter = 36cm

= 2 ( x + 2x )

= 2x + 4x

= 36 = 6x

x = 36/6 = 6cm

breadth = 6cm

length = 12cm



hope it helps uu frnd

breath be x
