Question

The perimeer of a rectangular sheet is 40 feet. If the length of the sheet is three times the breadth, find its dimensions.​

Answer 1

Answer:

length=15 feet,breadth=5 feet

Step-by-step explanation:

GIVEN: 2(length+breadth)=40  -(1)

             length=(3)breadth        -(2)

Substitute equation(1) in equation(2)

2((3)breadth+breadth)=40

2((4)breadth)=40

(8)breadth=40

breadth=40/5

breadth=5 feet  -(3)

Substitute equation(3) in equation(2)

length=(3)(5)

length=15 feet
