the width of a rectangle is two third of its length if the perimeter of the rectangle is is 135 CM find its dimensions
Answers
Let length of the rectangle be x cm
Width of the rectangle = b =( 2/3 )x
Perimeter = 2(l+b) = 135 cm
2( x+ 2x/ 3 ) = 135
2( 3x+ 2x / 3 ) = 135
2 (5x/ 3) = 135
10x = 405
x= 40.5 cm
Width = 2/3 * 40.5 = 81 / 3 = 27cm
Dimension of the rectangle = 40.5 x 27 cm.
[
check
Length = 40.5 cm
Breadth = 27cm
Perimeter = 2(l + b )= 2(40.5+27) = 2(67.5) = 135cm
hope it will help uh
Answer:
answer is 135 .
Step-by-step explanation:
Let length of the rectangle be x cm
Width of the rectangle = b =( 2/3 )x
Perimeter = 2(l+b) = 135 cm
2( x+ 2x/ 3 ) = 135The width of a rectangle is two-thirds of its length. If the perimeter of the triangle is 135 cm, what is the dimension of the rectangle?
Let length of the rectangle be x cm
Width of the rectangle = b =( 2/3 )x
Perimeter = 2(l+b) = 135 cm
2( x+ 2x/ 3 ) = 135
2( 3x+ 2x / 3 ) = 135
2 (5x/ 3) = 135
10x = 405
x= 40.5 cm
Width = 2/3 * 40.5 = 81 / 3 = 27cm
Dimension of the rectangle = 40.5 x 27 cmLength = 40.5 cm
Breadth = 27cm
Perimeter = 2(l + b )= 2(40.5+27) = 2(67.5) = 135cm
