Question

the length of a rectangle is 15 cm more than the breadth its perimeter is 174 find out the lenghth and breadthv​

Answer 1

Answer:

Let the width be #x# and length be #(x+3)#.

now, we have,

#Perimeter=2(l+w)#

#58 cm=2(x+x+3)#

#4x+6=58 cm#

#4x=52 cm#

#x=52/4 cm#

#:. x=13 cm#

So, width = #x# =13 cm

and, length = #x+3# = 13 cm +3 =16 cm

Answer 2

Step-by-step explanation:

x+x+15=174

2x=174-15

2x=159

x=159÷2

x=79.5

breadth =79.5

length =79.5+15=94.5
