Answer 1

Answer:

A rectangle has a perimeter of 130 centimeters. If the length of the rectangle is 4 times its width, find the dimensions of the rectangle.

---------------

width:: x

length:: 4x

----

perimeter = 2(length + width)

 

130 = 2(5x)

x = 13 (width)

4x = 52 (length)

hope it will help u

Answer 2

Given : Length of a rectangle is 4 times the breadth

Perimeter is 130 cm

To find : Length and Breadth

Solution :

Let the breadth be x cm

and length be 4x cm

According to the given condition

2(length + breadth) = Perimeter

➾ 2(4x + x) = 130

➾ 2(5x) = 130

➾ 10x = 130

∴ x = 13

∴ Length ➾ 4x

➾ 4 × 13

➾ 52 cm

∴ Breadth ➾ x

➾ 13 cm

∴ The length is 52 cm and breadth is 13 cm
