Question

What are the length and width of a rectangle if the area is 13 1/2 square units and the length of the one side is 1/5 of measure of the perimeter.

Answer 1

Perimeter of a rectangle = 2(l+b)
Area of a rectangle = l*b

Answer 2

Can someone explain the reasoning please.

Answer 3

and according to this question,
l = 1/5 of perimeter = 1/5 (2(l+b))

Answer 4

I'm a little confused.

Answer 5

@sauravshakya- I'm a little confused on your answer

Answer 6

What is the length of the rectangle?

Answer 7

length=\({1\over5} {\times} 2(L+B)\)

Answer 8

now let the width be x. then
\(\LARGE {(x) \times 2(L+B) \over 5}=13 \frac{1}{2}\)

Answer 9

\(\LARGE{x \times 2L+2B \over 5}={27 \over2}\)
\(\LARGE{x \times 2L + 2x={27\over2} \times 5}\)
