Question

The width of a rectangle is two - thirds its length . if the perimeter is 90 cm find its dimensions of the rectangle

Answer 1

Answer:

length=27,breadth/width =18

Step-by-step explanation:

width=breadth=2/3 of length ....(1)

perimeter of rectangle =2×(l+b)

2×(l+b)=90 (given in question)

b=2/3×l (from (1))

(b=breadth, l=length)

2×(l+2/3l)=90

2×(5/3l)=90

5/3×length=90/2

5/3×length =45

length =45×3/5

length =27

breadth =2/3of length

breadth =2/3×27=18
