Question

Convert to an equation: -
Length of a rectangle is 5 cm more than twice the width. The perimeter is 65 cm

Answer 1

Answer:

l=5+2b

area of rectangle= l×b

(5+2b)b

5b+2b²=1950

on finding D

we get, b=30cm

then l,

5+60

=65cm

Step-by-step explanation:

Answer 2

width - x

length - 5(2x)

( according to the question)

Step-by-step explanation:

perimeter = 2( l+b)

65cm = 2( x + 5( 2x) )

65xm = 2x + 10x

65cm = 12x

65/12 = 12
